[0002] Gypsum is a monoclinic mineral and a hydrate whose main chemical component is calcium sulfate (CaSO4). Gypsum is a widely used industrial material and building material. The most widely used natural gypsum is dihydrate gypsum, whose active ingredient is calcium sulfate dihydrate. Gypsum is generally graded according to the content of calcium sulfate dihydrate in the ore. Gypsum has a wide range of applications and a wide variety of products. Different uses have different requirements for the quality of gypsum raw materials. High-grade gypsum is mostly used as raw material for the production of special gypsum products, such as food, medicine, art, models and chemical fillers; gypsum ores with a dihydrate calcium sulfate content of less than 60% are rarely used; gypsum ores with a dihydrate calcium sulfate content of more than 60% are used in various fields such as building materials and construction according to their different contents.
