Gypsum processing and use - Humanitarian Library

2017-5-8  Gypsum rock is usually white or colourless, although it may sometimes have grey, yellow, pink, or brown hues. Gypsum is much softer than minerals of similar colour, such as calcite or quartz, and is the only one that can be scratched with a fingernail. If a piece of gypsum rock is held over a flame it will turn cloudy and opaque and give off water.

Gypsum - Chemical Formula, Properties, Types, Uses and

Gypsum rock is first mined or quarried, then crushed and ground to a fine powder. It then goes through a process called calcining where heat at 350 degrees is supplied to the gypsum powder which removes 3/4 th of the water molecules. Hemihydrate is the name of calcined gypsum which is then used in gypsum board, gypsum plaster, and other products.
