The first magnesium metal extracted from sea-water was produced by Dow Chemicals at their Freeport, Texas plant in 1948. The Freeport facility operated until 1998, but, presently, the only remaining salt water magnesium producer is the Dead Sea Magnesium Ltd. (Israel)—a joint venture between Israel Chemicals Ltd. and Volkswagen AG.
Magnesium derives its name from magnesite, a magnesium carbonate mineral. Different mining techniques are mining magnesium ores like dolomite and carnallite. The magnesium metal is obtained through the electrolytic refining of magnesium chloride.
The invention provides a process for producing magnesium hydroxide and calcium carbonate by the dolomite conversion method. The process comprises the following steps: calcining dolomite, carrying out a digestion reaction on dolomite and water and refining so as to obtain a refined slurry of calcium hydrate and magnesium hydroxide; reacting the slurry with an ammonium chloride solution to ...

from natural dolomite with simple apparatus was worked out. In the first stage dolomite was converted into magnesium sulfate and then into basic magnesium carbonate by combination with citric and acetic acids. However, magnesium aspartate was prepared by converting magnesium sulfate into hydroxide and then combining it with aspartic acid.
Magnesia, the primary magnesium compound, is produced at three facilities. Exhibits 1 through 3 present the names and locations of facilities involved in the production of magnesium, magnesium metal, and magnesia from brines, respectively. Magnetite and dolomite, which have a theoretical magnesium content of 47.6% and 22%, respectively, comprise

Magnesium (Mg) is the eighth most abundant element and constitutes about 2% of the Earth's crust, and it is the third most plentiful element dissolved in seawater. Although magnesium is found in over 60 minerals, only dolomite, magnesite, brucite, carnallite, and olivine are of commercial importance. Magnesium and other magnesium compounds are also produced from seawater,

Large quantities of processed dolomite are used in the production of float glass. In horticulture, dolomite and dolomitic limestone are added to soils and soilless potting mixes as a pH buffer and as a magnesium source. Dolomite is also used as the substrate in marine (saltwater) aquariums to help buffer changes in pH of the water.
Magnesium sulfate is produced as the end product With the tailings of higher magnesium content, while from the tailings with lower magnesium content, magnesium hydroxide is produced, because in this case, the lower magnesium content does not produce sufficiently concentrated magnesium sulfate solution to crystallize the salt.
The method [6] of obtaining magnesium oxide from calcined dolomite, in combination with the production of soda, by treating dolomite milk with a distillation liquid of soda production, consists in separating the solid phase from the resulting suspension, washing the precipitate, repulping it in water, carbonizing the resulting
