Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.

The Role of Drying in Gypsum Mineral Processing. After gypsum ore is extracted from mines or quarries, it is crushed and stockpiled as needed. If the gypsum ore''s moisture content is greater than weight percent, then the material requires drying. A gypsum dryer is commonly used to reduce the moisture content of the ore to the necessary level.

Rock Duster. Rock dusters are pressurized pieces of equipment that coal miners use to spray inert mineral dust over highly flammable coal dust. The inert dust helps prevent accidental fires and explosions. Shuttle Cars and Scoops. Coalminers use electricpowered shuttle cars to transport coal from the coal bed to safer points in the mine.

The rock is then crushed into smaller pieces and sent to the homogeniser, which allows for any variances in the gypsum size to be reduced, ensuring consistency in each bag of plaster. Calcination makes for perfect plaster . The rock from the homogeniser is ground down even further before it goes through what''s called the calcination process.
