Agua underground stream are always undersaturated with respect to gypsum (213 g L 1 compared to the 24 g L 1 of maximum concentration in pure water at 15 °C) (Klimchouk, 2000) Despite theThe correct formula of gypsum is CaSO 4:2H 2 O To keep the notation straight, we use here the short form, CaSO 4 Here and in the following, the shorter notation ‘log x’ is used for the decadic logarithm: log 10 x Tables of K sp values are given here Here we approximate K sp by the stoichiometric solubility product (Reminder: This is strictly valid for ideal solutions only, whereSolubility of Gypsum (CaSO4) Aqion
Gypsum Mineral | Uses and Properties
What is Gypsum? Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomiteGypsum (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 waterAmerica is blessed with abundant lowcost natural gypsum There is also an abundance of flue gas desulfurization gypsum produced as a byproduct of coalfired power plants As a result, the market for the phosphogypsum generated by the chemical processing of phosphate rock has traditionally been limited It has traditionally been piled on landPhosphogypsum Stacks

Crushing & Grinding of Gypsum
A different philosophy applies to the crushing and grinding of Gypsum Gypsum as a mineral (CaSO4·2H2O) is number 2 on the Mohs scale of hardness; only Talc is softer This would lead one to believe that it should be easy, to crush, like coal for example, andCalcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydratesIn the form of γanhydrite (the anhydrous form), it is used as a desiccantOne particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsumIt has many uses in industry All forms are white solids that are poorly soluble in waterCalcium sulfate Wikipedia
