WhatsApp: +86 18221755073Anhydrite is a mineral that belongs to the sulfate mineral group. Its name is derived from the Greek words "an" (without) and "hydros" (water), indicating its lack of water content. Anhydrite is composed of calcium sulfate (CaSO4) and is chemically very similar to another well-known sulfate mineral, gypsum (CaSO4·2H2O).
