2014-9-1  Particularly, these gypsum-rich materials may have reproduced some of the features that gypsophiles find beneficial in their natural habitat. Consistent for most materials in our study, gypsum or sulfur content has been claimed by some authors to increase growth and development of gypsophiles (Meyer, 1986, Ruiz et al., 2003). However, it does ...

GPR and seismic imaging in a gypsum quarry - ScienceDirect

2000-10-1  A gypsum quarry in western Europe has revealed stability problems which require local reinforcement. The galleries concerned have a section of approximately 6 m in width and 7 m in height; the pillars have a square section, with a minimum side length of 7 m. During mining operations at the quarry, no special precautions had been implemented.

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.
