Introduction
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. It can be used as cement retarder, building products, model making, medical food additives, sulfuric acid production, paper filler, paint filler, etc. The most widely used natural gypsum is dihydrate gypsum. Its active ingredient is calcium sulfate dihydrate (CaSO4·2H2O). Generally, gypsum is graded according to the content of calcium sulfate dihydrate in the ore. High-grade gypsum is mostly used as raw material for the production of special gypsum products, such as food, medical, artwork, models and chemical fillers; gypsum mines with calcium sulfate dihydrate content of less than 60% are rarely used; more than 60% The gypsum ore, depending on its content, is used in various fields such as building materials and construction.
