Magnesium compounds USGS
Domestic Production and Use: Seawater and natural brines accounted for about 57% of magnesium compounds production in 2011. Magnesium oxide and other compounds were recovered from seawater by three companies in California, Delaware, and Florida; from well brines by one company in Michigan; and from lake brines by two companies in Utah.

In USA, secondary magnesium production increased from 13% to 30% during [8, 9, 10]. According to Roskill, world production of primary
Component for the production of magnesium carbonate and ...
Component for the production of magnesium carbonate and magnesium hydroxide. At saturation by CO 2 of aqueous suspension MgCO 3 dissolves due to formation of hydrogen Mg (HCO 3) 2. From the aqueous solutions in the absence of excess CO 2 allocated basic magnesium carbonates. Magnesium carbonate with some metals carbonates forms double salts. One of such salts isnatural mineral .

US Patent for Magnesium separation from dolomitic ...
Clear liquid leachate from the clarifier is then stirred with calcined dolomite (dolime) to precipitate its dissolved magnesium as is conventional in production of precipitated magnesium hydroxide. Magnesium oxide from the dolime adds to magnesium derived from leaching to increase the yield of magnesium hydroxide.

FIG. 2AMiddle) Dolomite, which serves as the basic in gredient for production of magnesium at Texas plant, is received, crushed and burned as it goes from right to left through the facilities shown here.
Pidgeon process Wikipedia
In the last 10 years, the Pidgeon process has come to dominate world magnesium production. China is the dominant magnesium metal supplier, relying almost exclusively on this method. The silicothermic reduction of dolomite was first developed by Dr. Amati in 1938 at the University of Padua, where his thesis is archived.

Magnesium hydroxide | SMA Mineral
Magnesium hydroxide has a range of applications: It's mainly used in the manufacture of paper pulp as an alkali source for peroxide bleaching of mechanical pulp and as a source of magnesium in the production of sulphate pulp. It is also used in the treatment of water and flue gases.
Magnesium hydroxide | Revolvy
Magnesium hydroxide Magnesium hydroxide is the inorganic compound with the chemical formula Mg(OH). It occurs in nature as the mineral brucite. It is a white solid with low solubility in water (K = ×10−12).[4] Magnesium hydroxide is a common component of antacids, such as milk of magnesia, as well as laxatives.

Extraction of Magnesium? ResearchGate
All Answers ( 5) 1. dolomite is dissolved with HCl acid. during the leaching test, CO2 gas released from dolomite can be stored and pressured so as to use precipitation stage. (see number 3). 2. impurities in solution obtained from leaching are precipitated by adding OH ions (you should use Mg(OH)2 because of purity of solution) 3.

Magnesium: current and alternative production routes
impurities in the primary stage that require further refining (Brooks et al ., 2006). The 'solvent' route is another carbothermic process (Brooks et al ., 2006). magnesium formed from reduction dissolved in the molten metal while the CO gas librates. choice of metal is one of the scientific issues facing this route.
