Phosphogypsum refers to the calcium sulfate hydrate formed as a by-product of the production of fertilizer from phosphate rock.It is mainly composed of gypsum (CaSO 4 ·2H 2 O). Although gypsum is a widely used material in the construction industry, phosphogypsum is usually not used, but is stored indefinitely because of its weak radioactivity.The long-range storage is controversial.

Chemical Gypsum Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O.[3] It is widely mined and is used as a fertilizer, and as the main constituent in many forms of plaster, blackboard chalk and wallboard.

Gypsum is made up of oxygen, calcium, sulfur, and water, and its chemical formula is CaSO 4 ·2H 2 O. Gypsum beds were formed due to the evaporation of water from the massive prehistoric sea basins. When water evaporates, the minerals present in it become concentrated, and crystallize.

Gypsum mineral is non-toxic and it is a very common sulfate. Gypsum is chemically known as calcium sulfate dihydrate. It consists of water, calcium sulfate attached to oxygen. The chemical formula of gypsum is CaSO 4.2H 2 O.

Of the total supply of crude gypsum, 24.5 million tons, including 800,000 tons of byproduct gypsum, 19.1 million tons was calcined for gypsum products, and 5.4 million tons was used mainly as a cement retarder or as agricultural land plaster. The calcined gypsum was sold as prefabricated products or as industrial or building plaster.
