Gypsum Mineral Uses and Properties

Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.,0:$3URFHHGLQJV % ,Rehandle percentages .associated with some mining methods in use in the Interior Province are reported as being on the order of 38 percent, though only part of tbe rehandle is due to a need to promote highwall and spoil pile stability in wet ground. For example, at one mine in a swampy area, average rehandle percentage isGeological Society, London, Engineering Geology Special,Gypsum dissolves in flowing water about one hundred times more rapidly than limestone, but at only about one thousandth the rate of halite. At Ripon Parks (Fig. 1) where Permian gypsum abuts the River Urea large block (3 m 3) of gypsum fell into the river and dissolved in 14 months.

Asbestos Content in Drywall & Joint Compound?

Even if the gypsum board itself did not contain asbestos this means that by weight the asbestos content of the wall system was about 0.25%. (Redmond 2011), "Sheetrock mud" is a synonym for drywall compound or joint compound that before 1978 may have contained asbestos fibers.
