The process starts by extracting gypsum rock deposits from the ground using a ‘JOY mine cutter’ that scores away at the face of the gypsum rock. This is then broken up and transported to the surface. It’s homogenising time
Gypsum - Wikipedia
Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as far back as the Archaean eon. Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins.

overhead. This method of gypsum mining produces approximately 90,000 to 160,000 tons of ore a year. The largest gypsum quarry in the world, Gold Bond’s Milford, Nova Scotia operation, produces four and a half to five million tons of ore per year. The quarry process begins by first removing the earth over the deposit. Then gypsum ore is drilled
Gypsum Calcining - Metallurgist & Mineral Processing Engineer
Gypsum is the crystalline stone compound CaSO4·2H2O. A close stone relation – and frequently occurring with Gypsum – is Anhydrite which is CaSO4. Gypsun has wide commercial use because relatively simple heat processing reduces it to Plaster of Paris. While Anhydrite can be converted to Gypsum and thence to Plaster of Paris, the procedure is not simple and is quite costly.
Gypsum | Bharat Mining
An important property of gypsum is that it is naturally fire-resistant. The main purpose of adding gypsum in the cement is to slow down the hydration process of cement once it is mixed with water. The process involved in hydration of cement is that, when the water is added into cement, it starts reacting with the C3A and hardens.
