Properties and Uses of Gypsum - ScienceStruck

    Gypsum, also known as hydrated calcium sulfate, is a mineral that can be commonly found in marine evaporites, and in Permian and Triassic sedimentary formations. It can also be found in saline lakes, shale, limestone, dolomitic limestone, sedimentary rocks, hot springs, and some caves, where the air is dry enough to facilitate the deposition of ...

    Apr 24, 2014 · Calcium Sulfate Minerals. Gypsum is the more common, hydrated form of calcium sulfate. In fact, it is the most common of all sulfate minerals. Gypsum's chemical formula is CaSO 4. 2H 2 O. The anhydrous (without water) mineral is called Anhydrite (CaSO 4).. Gypsum and Anhydrite both occur as primary minerals in Marine Evaporites.Evaporite deposits occur when sea water evaporates under .

    This paper aims to understand the fundamental interaction mechanism between molybdenite and kaolinite in gypsum solution using kerosene as collector. Micro-flotation tests were conducted to study the effect of gypsum solution on the flotation performance of mixed −74 μm molybdenite and −10 μm kaolinite mineral. The results showed that the recovery of molybdenite decreased from 86% to 74% ...

    Gypsum CaSO4 2H2O - Handbook of Mineralogy

    Occurrence: A common constituent of sedimentary rocks, particularly marine salt deposits, and soils formed directly by evaporation or later by hydration of anhydrite. Formed by the reaction between sulfuric acid and carbonate rock in oxidizing sulfide deposits, and by the action of sulfurous volcanic gases on surrounding Ca-bearing rock.
