The gypsum used in construction is semi-hydrated gypsum processed by natural bihydrate gypsum, also known as calcined gypsum. Varieties of gypsum will be produced when the natural dihydrate gypsum is processed with the change of heating methods and temperatures. The main production procedures are breaking, heating and grinding.

Another key process in making gypsum is heating. This helps achieving the desired moisture content of the gypsym. To dry the product, feed the fine raw materials into the hot gas flow of the calciner. It is important to control and keep the temperature in check when operating gypsum making equipment.

There are five basic stages in gypsum processing: Excavation is sometimes carried out by digging out an area of ground where the gypsum is located using open-cast techniques. To reach deeper deposits drift or shaft mines may be needed. The drilling and digging equipment is applied to dig out the gypsum ore in excavation stages.

The production process of gypsum products can be broken down into four stages: exploration, quarrying, processing, panel production. The data resulted from the first process, i.e., the exploration process is used to determine the configurations of the components used in the later stages of gypsum production.

The desulphogypsum produced by the wet process is highly pure calcium sulphate dihydrate. Some impurities do not influence the reactions in the CaSO 4 –H 2 O system. However, if the SO 2 sorbing agent is introduced to the flue gas stream without de-dusting or directly to the furnace, complex desulphurization products are formed.
