Preparation process of magnesium chloride magnesium oxide or magnesite with hydrochloric acid to produce. Are the presence of magnesium chloride in sea water and brine.
Magnesium chloride shape: flake, block, crystals, granules or powder. Content is to 46% as magnesium chloride hexahydrate, 99% of anhydrous magnesium chloride. Raw material for smelting magnesium is magnesium chloride electrolysis, it mainly from the drying sea salt brine. For cards used for electrolysis of anhydrous magnesium chloride must be MgCl2*6H2O by heating in hydrogen chloride in streams, made it to dehydrate.
