Calcium sulphate contains one atom of calcium and Sulphur and four atoms of oxygen. It is an ionic compound which constitutes one calcium cation and one sulphate anion (polyatomic ion). Calcium ion has +2 valency while sulphate polyatomic ion shows -2 valency. So, on combining they form a neutral compound calcium …

At Armstrong Quarry, baryte, galena, marcasite, pyrite and sphalerite are concentrated in and around calcite nodules and in cavities produced by the dissolution of calcium sulphate evaporites.
From the Early Dynastic Period on, the Egyptians quarried a type of stone that is frequently referred to as alabaster, but is in fact travertine (a type of limestone - calcium carbonate). It is a whitish, slightly translucent stone (often with veins of another colour) which occurs mainly in Middle Egypt, particularly between Miniya and Asiut.The best known and most …

Calcium sulphate is the cell salt of the joints and the cartilage. Also liver and bile can be strengthened by calcium sulphate. In respect with the connection to the joints one can use calcium sulphate against arthrosis and rheumatic arthritis. Another typical operational area of calcium sulphate is his ability to relieve suppurating processes.
