Anshan talcum powder is usually used for potted plants magnesium-deficient crops, such as tomatoes, potatoes, roses, etc. The advantage of magnesium sulfate over other fertilizers is its higher solubility. Magnesium sulfate is also used as a bath salt. Magnesium sulfate, anhydrous magnesium sulfate, is a compound containing magnesium. Anhydrous magnesium sulfate is a commonly used chemical drying reagent. Oblique columnar crystals, odorless, bitter, clinically used for catharsis, choleretic, anticonvulsant, eclampsia, tetanus hypertension

It is obtained by decomposing neutralizing magnesium oxide, magnesium hydroxide, magnesium carbonate, rhodochloite, the like with sulfuric acid. There are also raw materials for the production of potassium chloride, which are mixed with the magnesium-containing mother liquor after bromine production in proportion, then cooled crystallized to obtain crude magnesium sulfate, which is then heated, filtered, removed, cooled to obtain industrial magnesium sulfate. It can also be obtained by heating concentration of bittern, crystallization, carbonization of aqueous suspension of magnesium oxide gypsum.
