Rockets - They are one of the most enjoyable pyrotechnic devices. Small lightweight rockets can be made using Black powder, which is used popularly as rocket propellant and is easy to mix. We have explained the basic steps that can follow to make a simple rocket.

First make the black powder mix. Use Potassium Nitrate, Air Float Charcoal,80 Mesh Charcoal, Sulfur in the ratio of 16:6:3:4. This is a optimum mix ratio, grind all the mix into a container and make a fine free flowing powder. Pass it though a mesh preferably 20 Mesh steel mesh.

Take a 4 Oz Engine tube for making the Body of the rocket. Now ram the fine grained black powder mix into the tube up to 80% and a little air room. You can use a 'ram through funnel', which will make our task easy, the rammed materials inside the body of the rocket should be hard.

Now fill in clay after making it a little moist and fill it in the space where the room for air has been left. Now punch a thin hole in the clay using a thin object, say needle. This is for the fuse. A ready made fuse can be obtained from a firecracker or by coating a cotton string with the same black powder material.

Attach the fuse to the under part of the rocket body through the clay, also make a conical head of paper materials.

Now tape a long stick to the rocket for stability. The rocket is ready now, bury the stick in the sand upright and light the fuse, watch it skyrocket upwards.

Being little children we have dreams about whom are we going to be in their future. Though your dream was to fly into outer space, you chose to keep your feet on the ground and let your mind wonder and research. Being attentive, hard-working, intelligent and efficient you have every right to call yourself a scholar, but first of all you are to prove it to the others.

A scholar is a scientist researching the field of his interest and contributing to it. A scholar is doing a vital job: getting to the essence of things and makes an explanation, an outline, readable and understandable for the colleagues and interested individuals. Excellently written dissertation thesis is not enough to call oneself a bright scholar, for your research may be covered with dust and buried under a pile of similar works. You have to be genuinely interested in what you are doing and get some of your writing into your head for further research. If you want your masters thesis to be read and forgotten you may formulate your thesis statement in a "keep it simple" kind of way. You won't have to worry about your thesis drawing attention. But if you are concerned to show a completely new approach, or state a new point of view or you got luck and made an important discovery, your work can be published by mass media and bring you success. Top priority for every scholar is to help humans live in comfort, keep them informed and provide them with everything necessary for fair development and success. You are to create authority to communicate with other scholars on friendly terms and assist each other in doing research.

A scholar is never tired to investigate and try, experiment and risk. It can take years to come to a conclusion or a discovery, which, by the way, may turn out to be false eventually. A true scholar never gives up trying to find out the truth. Motivators are fame, recognition and a fortune if your discovery brings stable income. That is practically all, what ambitious people need in their lives. There is nothing more awarding than respect in your family, acclaim among colleagues, financial freedom and a bookshelf full of your editions that will make you famous forever.

Pearl Jewelry Fashion Trends For Modern Age

(category: Science, Word count: 561)
Share this article on: Facebook, Twitter, Whatsapp

The classic elegance and luster of pearls has become more of a curse than a blessing. They may be considered lovely jewelry but are usually relegated into the background, in stuffy events like weddings, christenings and coming out balls. Pearl necklaces have sometimes been equated with "squares", spinster aunts, grandmothers and the old South. Pearls have had a hard time competing with more edgy jewelry like the luscious and high-class gemstones like diamonds, rubies, sapphires, and even semi-precious stones like opal and garnet.

Pearls have therefore become remnants of the past than beautiful gems that can be used as modern accessories. That has changed. Pearls have made a huge comeback into the modern scene just a few years ago. They did not really leave the fashion world but only had limited and specialized use. Today, pearls can be found in almost all kinds of fashion-related items.

The reason for this is the accessibility of pearls in the form of freshwater pearls. Japan has started this industry in the 1920s by culturing pearls using freshwater mussels. However, it has declined production but China has claimed the production of cultured pearls because of the high demand for them.

Donor mussels are inserted with irritants that form the pearls and some of these mussels can produce up to 40 freshwater pearls. The pearls are not as high-quality as the ones made naturally but the color and shape can be controlled and some freshwater pearls can be breathtakingly beautiful as natural ones.

A pearl strand belonging to Mary, Queen of Scots dating from 1550 is made of freshwater pearls. Scotland has been cultivating freshwater pearls, as well as North America but the extinction of almost 35 species of mussels in Europe and America has left Asia with this booming industry.

Because of its reentry into the world of edgy fashion, more and more pearl companies are striving to provide jewelry ideas for the modern woman. There are many ways that freshwater pearls can be used and integrated into a woman's fashion sense. They can be used as accessories. Pearl jewelry today tries to incorporate contemporary design and color into pearl necklaces. The classic pearl necklace and pearl choker has given way to long strands of irregularly shaped freshwater pearls in all sizes and colors. They can be paired with casual wear such as jeans, blouses and short dresses.

Pearl bracelets and pearl earrings come in magnificent colors such as red, turquoise and canary yellow that makes any outfit pop. Other jewelry options for pearls include adding beads made of semi-precious stones or crystals.

Pearls have dominated all aspects of the jewelry trade. Even the mother-of-pearl shell of mollusks is used for inlay work on bracelets with freshwater pearls as accentuating items. Pendants for necklaces and rings are now also popularly made of freshwater pearls. Even younger people have seen the flexibility and the touch of beauty that pearls give to an otherwise ordinary outfit and include these accessories while shopping.

Office women rely on pearl necklaces to give them that polished corporate look. Jewelry designers are coming up with more and more ideas for pearls. Edgy and contemporary jewelry designs have freshwater pearls in them, either as the main piece or an accentuating item. Indeed, pearls are here to stay.

A Bird S Eye View Of Wolves

(category: Science, Word count: 402)
Share this article on: Facebook, Twitter, Whatsapp

Wolves are a widely studied species in Yellowstone. Since wolves were reintroduced to the park after an absence of almost 80 years, scientists spend a lot of time studying the animals' unique behavior.

"Our knowledge of wolves is vast due to decades of research around the world," said Tom Oliff, chief of natural resources. "The ability to oversee wolves in the wild has been challenging and the knowledge gained through direct observations of behavior is invaluable to understanding the species."

The best way to study wolf movement is from the air. The Raven's Eye View of Yellowstone is a component of the Aerial Eyes project that is supported by Yellowstone Park Foundation (www.ypf.org) in cooperation with Canon U.S.A. The Eyes on Yellowstone program is made possible by Canon; it provides funding and digital technology to support an array of park resource management and education programs.

Using a Canon EOS 20D digital camera body with a 100-400EF lens (f 4.5-5.6) as a scientific tool, wolf biologists Doug Smith and Dan Stahler are changing the way quantitative and qualitative wolf data are gathered and studied.

The scientists have documented various behavior-from hunting prey, to raising pups, to interacting with various species throughout the park. The details, however, remain difficult to see with the naked eye, particularly when using the routine monitoring technique of aerial radio tracking from fixed-wing aircraft flying high overhead.

The digital equipment has helped revolutionize this research. High-resolution digital photographs that can be taken several hundred feet above ground and later enhanced have, in a short time, opened new windows to studying wolf ecology and behavior.

"This is a major breakthrough for wolf research, providing first-of-its-kind results," said Stahler. "Of particular value is the identification of individual wolves and the role each plays in the pack while engaged in different activities. Determining the presence and number of pups in a litter, or whether or not a certain member of the pack is still alive, can now be readily discernable through studying photographs taken with quality digital camera equipment."

Digital photography has changed science, and it has allowed Yellowstone scientists to gather data never obtained by any other wolf research project. The combination of digital imaging and enhanced lens quality are key scientific tools to help study and understand wolves.

What Is Iridology

(category: Science, Word count: 681)
Share this article on: Facebook, Twitter, Whatsapp

In 1950, a chiropractor from America named Bernard Jensen began teaching students about the necessity of using natural foods to detoxify the body. He developed a method by which the color of the iris was used to indicate the presence of different toxins. American iridology was born.

However, iridology, or the study of disease using the color of the iris and certain color and thickness of lines across the eyeball originated in Europe, when a physician from Hungary and a Swedish pastor both noticed iris markings in connection with disease.

The physician-Ignatz von Peczely accidentally injured an owl as a child, breaking its leg. While nursing the owl back to health, the young von Peczely noticed that the thick black mark that appeared in the owl's eye after the injury began to lessen as the owl healed. He never forgot it, and as an adult practicing his profession, he recoded that patients with bone fractures experienced the same black mark across the iris.

The Swedish pastor-Nils Liljequist-was exposed to malaria as a young man and while recieveing the treatment of quinine and iodine noticed that his blue eyes began to grow darker as the drugs built up in his system. He grew up to study homeopathic medicine and recorded similar reactions in clients who came to him for detoxification purposes.

It has been said that the eyes are the mirror to the soul. The famous Greek physician Hippocrates believed that they were also the mirror to the body-specifically for the purpose of determining various ailments. He too recorded the presence of black marks across the iris of fractured bones in his patients, and a change in the color of the eye of patients coming down with diseases.

Unfortunately, iridology cannot be used to determine a specific disease.

Practitioners of iridology use it to help patients as a preventative measure understand basic health problems in order to refer them to specialists if needed. The belief is that if a disease is detected in the very early stages it can be prevented from spreading further. The colored part of the eye-the iris-is studied for these markings and color changes by isolating the iris and taking pictures of it with a very strong lens. The process takes about an hour and is painless. The photos are then blown up and gone over with a magnifying glass by the iridologist and used to determine and identify potential ailments.

Most of these ailments are believed to be hereditary, and the patients predisposition to toxicity and disease is determined not only by the photos but with an extensive interview of family medical history. This holistic concept is well accepted by other disciplines of alternative medicine, as it is a fact that all parts of the body are related, especially when used to warn the body of an impending degenerative disease.

Under this theory, the color changes in the eyes at the very onset of the degenerative disease are used by the body to indicate an upcoming health problem, and to warn the body to seek preventative measures. The concept is not far fetched at all-take the example of chiropractors using the process of correcting the spinal alignment to help internal organs. Even conventional physicians check the eyes for signs of sickness. (Blood vessel size is an indication of the level of cholesterol.)

There is, however, some criticism toward iridology as practitioners (especially in the United States) are often not fully or thoroughly trained, as the courses offered are usually no more than two to three days in length and are put on by marketing companies who offer "certification" as an iridologist to their distributors. The result is the potential for over diagnosis with the distributor pushing their products through their "specialist."

This tendency toward American consumerism and over marketing has given iridology a black eye (no pun intended) as a reputable form of medicine.

When seeking an iridologist, find one who has been certified by the Institute for Applied Iridology or by the International Iridology Research Association in Solana Beach, CA.

Big Bang Booming Back To The Future

(category: Science, Word count: 1150)
Share this article on: Facebook, Twitter, Whatsapp

Theoretical cosmologists spend much of their time perfecting what is now known as the 'Big Bang' theory. This concept originates from ideas percolating in the minds of scientists, theologians and astronomers down through the ages. However, much of what they consider as proof for the 'Big Bang' is dependent upon uncontrolled experimentation that is molded to meet their expectations.

Then God said, "Let there be light," and there was light. This ancient description of the creation of the universe found in the Book of Genesis may be accurate after all. The big bang theory describes the beginning of the universe as having been precipitated from an infinitesimally small point. In this small volume, all matter and energy was concentrated until its contents exploded in either a smooth expansion or an incredibly violent energetic explosion that formed the planets, stars and galaxies. Originally this theory had competition from what is called the 'steady state' theory whereby the universe is forever expanding and new matter and energy is created spontaneously within the space left by the receding galaxies. However, empirical observations have directed astronomers and scientists into the acceptance of the big bang model. But how did we get to this point in our understanding?

In the early part of the twentieth century the American astronomer Vesto Slipher and the German Carl Wirtz made some important astronomical discoveries. Using spectral analysis, Slipher deciphered the mixtures of gases contained in planetary atmospheres as well as nebulae. What distinguishes his findings is the discovery that most if not all galaxies outside of our own demonstrate what is called a 'Red Shift.' This shift is simply a change in the wavelength of the light emitted by those objects under investigation towards a longer wavelength. Wirtz similarly catalogued many red shifts of the nebulae which he chose to study. But it was still to early for them to realize the full potential meaning of their observations. That would wait until Einstein's General Relativity would be interpreted by other scientists through further mathematical analysis.

His contemporaries demonstrated to Einstein that his new Theory of General Relativity published in 1916 was not compatible with a 'static' universe of space time. The theory predicted an expanding or collapsing universe but not a fixed cosmos. Because he personally believed the universe to be an invariable space time continuum, Einstein engaged in a degree of scientific legerdemain. To correct what he perceived to be as 'flaws' in his theory he added the contrivance of a cosmological constant known as lambda to force the static universe into reality. Einstein's view of perfection in an unchanging space time continuum had led him down a blind alley as much as Aristotle's concept of perfection had brought that great philosopher into the error of believing in a static Earth at the center of the universe.

But even with the addition of the cosmological constant lambda, the universe was still found to be unstable and this whole affair would later be viewed by Einstein as his "greatest blunder." His cosmological acrobatics behind him, Einstein yielded the stage to others for a clearer understanding of his own theory. It fell to Alexander Alexandrovich Friedmann to consider the consequences of General Relativity without the constant lambda interfering with his study of these relationships. In doing so, the Russian mathematician and cosmologist derived the solution which predicts an ever expanding cosmological structure (1922), a prediction which was disagreeable with Einstein's concept of universal perfection. A couple of years later, Friedmann published his findings in "About the Possibility of a World with Constant Negative Curvature of Space." But the entire hypothetical construct still lacked a complete verbalization mathematically and theoretically.

Enter the Reverend Father Georges Lemaitre, a Catholic priest from Belgium. Rev. Fr. Lemaitre provided the equations necessary to formulate the basis of Big Bang theory in his work entitled "Hypothesis of the Primeval Atom." He postulated that the universe began as a primordial atom of infinitesimal volume and enormous mass energy as well as space and time and everything else comprising the future universe. At some point the universe began with the explosion of this super atom. Lemaitre published his theoretical ideas between the years 1927 and 1933 and speculated that the movement of the nebulae demonstrated the validity of the explosion of his cosmic super atom. Unfortunately, he also wrongly believed that cosmic rays might be an after effect of the super atom's big bang. These are now known to be generated not from a universal conflagration but from galactic sources unrelated to the big bang.

However, the new theory still lacked a major source of observational support. This would be provided by Edwin Hubble's observations of the redshift of galaxies. Taking up where Slipher and Wirtz left off, Hubble employed a novel technique to discern the properties of the galactic movements. By choosing to observe stars that are known as Cepheid Variables he could more accurately make measurements. Cepheids are a type of star that brighten and darken and lighten back up in regular periods of time that are well known. Cepheids that have identical cycle times of brightening darkening and brightening again also have identical or nearly identical luminosity. Thus, if one compares the length of the cycle to the amount of light apparent to the observer it is possible to accurately prepare an estimate of the distance to the cepheid.

In this manner, Hubble had found that the nebulae or galaxies exhibited a galactic red shift; in other words, that galaxies were receding away from ours at a speed which is correlated directly with the distance between our vantage point and the galaxy being studied. The further away the galaxies were the faster they appeared to be going in moving away from us. The results of these investigations is now known as Hubble's Law. Essentially, this law states that universe is in an ever expanding mode whereby the intergalactic distances continue to grow without bound into infinity. Hubble's Law depends upon the shifting of the wavelength of light and after having been delineated in 1929 has been subsequently proven over and over again. Further, Hubble's constant has been recalculated to a more 'perfect' value and retains a great probability of being 'recomputed' in the future based upon new observations.

Thus, it should be clear to the reader that our scientists have a fateful habit of introducing their preconceived notions of beauty into their models. From Aristotle's static Earth to Einstein's greatest blunder, the constant which forces a static universe, we proceed only from the wisdom of our weak minds. The more things change the more things stay the same. Man's hubris knows no limits in our attempts to understand things without the wisdom to comprehend its underlying meaning. Humble we are not. We are making the same mistakes we always have. Back to the future. To be continued...

Reversing Mother Nature Part Three

(category: Science, Word count: 1497)
Share this article on: Facebook, Twitter, Whatsapp

We talked to North America's leading In Situ Leach (ISL) uranium mining engineers, and had them explain exactly how ISL worked. Most of the significant ISL operations in the United States were designed and/or constructed by these engineers. They explained how ISL mining is really just reversing the process of Mother Nature.

CLEANING UP THE PROJECT

Not so fast. Shipping the uranium out of the ISL plant isn't the final step. The water has to be cleaned up, the property returned to its original condition. If done properly, then the footprint of the ISL uranium operation should have been nearly erased. In an earlier article, "Wyoming Uranium: Now and the Future," we talked to Pat Drummond at Smith Ranch about this process:

The company is meticulous in restoring the landscape as well. Any restoration work on the surface is called "reclamation." That can involve farming. "When we start a well field, we have to, by license, remove the topsoil and store it somewhere," Drummond explained. "When we go back to reclaim the property, we take all the pipes out, we take the houses down, and cut our wells off. It's all identified. We put an ID marker on the well. In 50 years time, when Farmer Joe comes around and wonders what was there, the state can say, 'That was a uranium well.' From the time we've stopped mining, we put everything back to normal."

The one item we did not address at the time was cleaning up the water after the orebody has been mined out. Why is restoring the water back to background important? "In the mining process, you're basically elevating sulfate," explained Anthony. "You're also elevating calcium because you're lowering the pH a little bit, down to 6.5 to 7. Because you run it across the ion exchange circuits, you get a little leakage of chlorides into the lixiviant." Subsequently, the water will have sulfate, chloride, calcium and bicarbonate circulating within it. "When you add carbon dioxide, you're forming bicarbonate," Anthony noted. "These are the major ion groups you are elevating during the mining process." He also added that in some projects, you may get arsenic, vanadium and/or selenium. "They all go into the solution so that at the end of your mining process, these ions will be elevated above their baseline values." The water will need to undergo a purification process to return them back to a quality consistent with baseline values."

What does the ISL operator do with the water once the facility has mined out the uranium? There are three options, which we discussed with Glenn Catchpole, who has also set up previous ISL operations. In 1996, Catchpole was the General Manager and Managing Director of the Inkai uranium solution mining project in Kazakhstan. He is currently the Chief Executive of Uranerz Energy. "Here's my order of priority: If you have a receiver formation for deep disposal on your project, that's my first choice." Sometimes, a project may not have access to a deep disposal aquifer, warned Catchpole.

The water is sent down the receiver formation, down about 4000 feet. "You're usually sending this water to a formation that is very briny, a poorer quality than what you're sending down," Anthony pointed out. Another option, according to Catchpole, would be operations ponds, or evaporating ponds, where the water is evaporated. A third option is "land applied." Catchpole explained this was for land application. "You take your waste stream, you treat it to remove the certain level of impurities, according to the government requirement, and then you're allowed to disperse it on the land surface, as if you were irrigating." When applied to the land, it is soaking into the land. "It's growing grass, and it's going into the groundwater system," concluded Catchpole, "Whatever water quality standard they allow for you to put that water in the land, they want to ensure it doesn't accumulate some particular chemical over time that is going to build up and contaminate the land."

Generally, during the restoration process, the water is circulated through the barren orebody about eight times. It's another instance of pore volumes - eight more times through the sandstone formation. Anthony explained, "Normally, the first pore volume is evacuated and disposed of via a disposal well." But he warned, "This will cause an inflow of surrounding native water back into the mine zone. The resulting water is pumped to the surface and processed through a reverse osmosis unit." Anthony compared this to the desalination of seawater. "The reverse osmosis equipment acts like an 'ion filter,' allowing pure water to pass through a membrane and filtering out ions of sulfate, calcium, uranium, bicarbonate and so forth," Anthony explained.

Two streams of water are produced by the reverse osmosis unit. One stream is called "product water," and is normally consistent with drinking water quality. The smaller stream of water is called "brine." It contains, according to Anthony, "95 percent of all the dissolved ions that were in solution." He said, "The brine is disposed down a deep well into an underground formation, which is typically not suitable for any use."

CONCLUSION

For all the lip service and media attention paid to the environmental movement in terms of financial support, recognition and respect, it is the ISL miner who cares more about the environment, about preserving Mother Nature. Environmentalists remain ignorant of, or care not to publicize, the dangers of coal-fired electrical generation. Mining and burning coal to generate power for industry and residential electricity poses a greater threat to Mother Nature than ISL mining and nuclear power-generated electricity. No more evident a case in point is New Mexico, where the Navajo Nation "banned" uranium mining, because their president was misled by environmentalists in believing ISL uranium mining could pose a threat to groundwater. At the same time, the Navajo Nation enjoys over $100 million in coal royalties each year, as their air is polluted by carcinogens filling their air from coal mining in the San Juan Basin and coal-fired plants, which produce most of their electricity. It is time for the world's environmentalist movements to wake up and smell the air they are breathing.

Unfortunately, ISL uranium mining will not replace conventional uranium mining in many deposits across the world. According to the World Nuclear Association, ISL mining accounted for 21 percent of worldwide uranium mining in 2004. "The overriding constraint of ISL is the technology is only applicable to selected uranium deposits," Stover cautioned. "It's those deposits wherein the uranium ore resides in a permeable environment, where you can flow water through the deposit and where you can bring the dissolved oxygen and carbon dioxide into contact with the uranium." Stover explained that, during the evolution of ISL mining, a number of projects failed because the uranium was associated with organic material, was not accessible to the leaching solution, or the uranium was tied up in clays or shale-like material. "They were not able to flow fluid through it," explained Stover. "The key issue at the onset is a careful characterization of the host environment in which the uranium exists."

The key advantage to ISL is the far lower capital costs to start up a project, compared to the hundreds of millions required for a conventional mining and mill complex. For example, UR-Energy's William Boberg and Uranerz Energy's Glenn Catchpole both believe they can install an ISL operation on their Wyoming properties for as little as $10 million. Labor costs are also less. Doug Norris pointed out, "In its heyday, the Highland mine probably had 4,000 working in it." By comparison, Cameco's Smith-Highland ranch in Wyoming may soon ramp up to nearly 100 employees. "We're talking about installing a centralized water treatment plant supported by a large number of water wells, typically completed with PVC," Stover explained. "That's in contrast with conventional mining, where you have extensive earth moving, in the case of an open pit or extensive underground workings, and a more complicated, much larger processing plant."

In terms of environmental impact, ISL offers something sensible to the environmentalists. "ISL is much less intrusive, and it is short lived," Stover said, echoing the sentiments of all who have been involved in this type of uranium mining. "It's acceptance by the general public is much more favorable," he concluded.

What does the future hold for ISL uranium mining in the United States? "Up until 2004, prices were flat," Norris pointed out. "The economic picture has just now switched to where mines can start coming on again, but it does take years to properly define where the ore is. It takes a lot of geologic drilling and time to decipher it. Then there are the regulatory requirements, and that can take several years. Even if everybody reacted right now to what's out there, it would still be several years, upwards of five years, before production jumped from its existing rate to 10 to 20 million pounds at the most."

Nitrous Oxide Laughing Gas Uses In Modern Society

(category: Science, Word count: 319)

Laughing gas, N2O, dinitrogen monoxide or to use its older name, nitrous oxide has a range of uses in our society. Most of these would have to fall into the category of non-essential.

Nitrous oxide is well known as a dental anaesthetic gas. Having gas at the dentist though, is much less common nowadays, because of accidents that have happened. There have been occasions where patients have had the wrong percentage of oxygen mixed with the nitrous oxide they were given. The requirement in some states that a fully qualified anaesthetist is present when nitrous oxide is used. It is not as pleasant to be given nitrous oxide as it sounds, it often causes nausea and dizziness.

Whipped ice-cream uses nitrous oxide as the gas in the tiny bubbles. Nitrous oxide ice-cream chargers have caused death to individuals who have inhaled the gas directly. Nitrous oxide is not poisonous, but inhaled in large amounts, like this and without any added oxygen, it causes the lungs to collapse. Inhaling nitrous oxide in this way is illegal in many jurisdictions. Accidents have also occurred when people have confused nitrous oxide with the highly poisonous nitric oxide gas.

Nitrous oxide is used in rocket fuels and also by custom car enthusiasts to boost the performance of their engines. The nitrous oxide is a more powerful oxidizing agent than the 21% oxygen in the atmosphere. Temperatures in the engines are higher and specially designed valves are necessary to withstand the extra heat.

Nitrous oxide is extremely harmful to the atmosphere. It has 250 times the greenhouse gas effect as carbon dioxide. This means that 1 litre of nitrous oxide has the same climate changing effect as 250 litres of carbon dioxide. The quantities of nitrous oxide released to the atmosphere are small, so it still only contributes a small fraction of the total greenhouse effect.

ISL EXTRACTION AND PROCESSING

During ISL mining, water is pumped to the surface from production wells that contain uranium in very low concentrations, on the order of parts per million concentrations. The next step in the ISL process is to extract the uranium dicarbonate. Extraction is done by chemically exchanging ions inside a processing facility. "The ion exchange process is very analogous to a home Culligan
