2021-3-12 MOUNTING demands for magnesium for war purposes continue to emphasize interest in new processes for its production. Latest of these employs ferrosilicon to reduce calcined dolomite to free metallic magnesium which is then distilled from the reacting mass. Production of the light metal in the United States has so far been limited to the electrolysis of magnesium chloride obtained from natural ...

2016-8-25 To solve the problem, Zhang et al.7 proposed a novel process by which magnesium was extracted from pre-prepared dolomite pellets with ferrosilicon as reductant. In this method, powder materials including dolomite, ferrosilicon, fluorite and binder are mixed to produce pellets which are called pre-prepared dolomite pellets, and then calcined.

1996-11-15 Dolomite is, after calcite, the second most important and abundant of the carbonate minerals. Chemically and structurally, it may be regarded as calcite with half the calcium ions replaced by magnesium. Iron or manganese may substitute for magnesium in dolomite, forming isostructural series with ankerite and kutnohorite.
