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.

Typically, stucco is prepared by drying, grinding, and calcining natural gypsum rock (i.e., calcium sulfate dihydrate). The drying step in the manufacture of stucco includes passing crude gypsum rock through a rotary kiln to remove any moisture present in the rock from rain or snow, for example. The dried rock then is ground to a desired fineness.

Jun 26, 2021 Besides, the gypsum rock has prominent water softening characteristics, which may contribute to the complex energy conversion. Therefore, it is necessary to study the damage evolution based on the energy dissipation for gypsum rock subjected to water. In this paper, first, the mineral composition of gypsum rock was quantitatively characterized.

The UK is largely self-sufficient in gypsum. The material can be found in seams in the Pennines and the Midlands, but the biggest source of extraction is in East Sussex where mining extracts some 100,000 tonnes of gypsum a year from 100 m below the High Weald. The mined rock is reduced to powder through a process of crushing and grinding.

The energy required is a minor proportion of SAG mill power and this proportion falls as the liners wear (and lifting capacity falls) even when mill speed can be increased. The major proportion of mill power is used to turn over the mill charge. It follows that repeated ball-rock short-range low-energy impacts within the tumbling charge are
