Bischofite Research Paper

1. Abstract:

Magnesium is the lightest of all commonly used structural materials. It plays a central part in the manufacture and use of competing metal products. Global magnesium demand is forecast to see a compounded annual growth rate of 7.7% over the next five years. Traditionally magnesium is produced from dolomite and magnesite ore (Pidgeon process), as well as magnesium chloride containing salt brines (naturally occurring salt deposits). This literature survey focus mainly on Magnesium production from Bischofite (MgCl2.6H20), Bischofite (hydrated magnesium chloride) is mainly produced from sea water brine and is highly hygroscopic in nature, used in many chemical and medical industries. Bischofite is unique in purity and is the most biologically active mineral available in the world today.

This review summarizes crystallization processes of bischofite from concentrated brine and possible bischofite suspension …show more content…

Introduction:

Bischofite is a hydrous magnesium chloride mineral with formula MgCl2•6H2O. It is a divalent cation electrostatiscally balanced by two chlorine atoms, plus six water molecules for every other atom.

Bischofite is ecologically pure natural magnesium poly-mineral with a unique composition. It contains many macro- and micro-elements vital for human health, in much higher concentrations than can be found in sea or ocean salt. The main bischofite compound is magnesium chloride (up to 350g/L), moreover, it contains about 70 other elements as impurities including potassium, sodium, boron, calcium, silicon, molybdenum, silver and copper, etc

The mineral is very hygroscopic and must be stored in a closed vial. Bischofite deposits differ by their composition: some of them are salt basins where bischofite is mixed with other minerals such as carnallite, halite, kieserite and anhydrite. These are the so-called bischofite containing rocks which have pink-brown-yellow and orange-red colors. They contain 36–58% of

  • Percent Cu2 + In A Mineral Sample

    931 Words  | 4 Pages

    Purpose/ Methods The purpose of this experiment was to determine the mass percent Cu2+ in a mineral sample (Malachite), and a rock sample (copper ore). Through the process of spectroscopy, the students were able to determine the percent of copper that each sample yielded. The students were also able to apply the information to the theoretical value of copper in malachite to determine the percent error of the mineral mass percent. Furthermore, the methods used in the experiment provide insight into how mining companies determine whether a copper ore mining site will be profitable or not.

    From the AA spectrometer’s readings (conducted by Dr. Stephanie Le Clair), the absorbance was calculated for the Ca2+ and Mg2+ which were dissolved in the sample connected to the spectrometer through a tube. Following testing, graphs of light absorbance versus metal ion concentration were created, and the obtained equations from the trend line were used to translate the values into the corresponding concentration of CaCO3 (see

    In Russel Baker's essay, "The Art of Eating Spaghetti", he was trying to express that what you end up doing shouldn't be determined by how hard it will be, but instead by if you want to do it or not. He says that he felt that he wanted to be writer, but knew that it kids didn't just graduate and be a writer. At the end, he says, "Writing couldn't lead to a job after high school, and it was hardly honest work, but Mr. Fleagle had opened a door for me."

    Cookies have been around a long time (they probably originated as drops of grain paste spilled on hot rocks around a fire), but they became associated with Christmas in Europe in the 1500s. Gingerbread was a similar food, but laws restricted its baking to guildsman, however at the holidays these regulations were relaxed and people were allowed to bake their own at home, making a very special once a year treat. Gingerbread originated in the Crusades and was originally made using breadcrumbs, boiled with honey and seasoned heavily with spices. It was pressed onto cookie boards (carved slabs of wood with religious designs) and dried. Gingerbread evolved to become more secular and to use more modern ingredients.
