Uses for Gypsum Powder

19/11/2018Gypsum is a soft mineral that usually appears white or gray and is composed of translucent crystals. Gypsum deposits are found as sediment in areas that were once covered by water. When rock gypsum is heated, it releases the water molecules bonded to it, and the resulting product is anhydrous gypsum, a dry powder.

How Is Rock Gypsum Formed?

Gypsum appears white in absolutely pure form. However, it normally contains impurities that make the rock look brown, gray, pink or even black. Gypsum deposits are found interlayered with limestone or shale in flat beds. Gypsum deposits formed millions of years ago when the salt water oceans receded and caused the formation of inland dead seas.

The British Gypsum mining process

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.

The UK is largely self-sufficient in gypsum.

The mined rock is reduced to powder through a process of crushing and grinding.
