2007-5-18 · gypsum samples are also characterized by steep light-REE enrichment and, in some cases, REE concentrations greatly exceeding those of the adjacent granite. The data suggest that the R.EE content of the g;'psum is a product of effec-tive partitioning from the parental brines, which in turn reflects the R^EE distributions of the host granite acquired

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.

Gypsum: a review of its role in the deterioration of ...

2006-12-2 · The deterioration of buildings and monuments by gypsum is the result of crystallization cycles of this salt. Although gypsum can dehydrate to a hemihydrate, the mineral bassanite, and to an anhydrate, the mineral anhydrite, this reaction occurs in nature on a geological time scale and therefore it is unlikely to occur when gypsum is found on and in building materials. The CaSO4–H2O system ...
