Sources of Limestone, Gypsum, and Anhydrite for Dusting

Gypsum is a hydrous calcium sulphate; it grinds to a white powder, is not injurious as a dust, and is fairly low-priced, though not as abundant or as generally distributed as limestone. Anhydrite is the anhydrous form of cal-cium sulphate and occurs in varying quantities in many gypsum mines. It is harder than gypsum, gives a white

Limestone. Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO3)2.
