Dolomite Calcium Magnesium Carbonate CaMg(CO3)2 In England, dolomite has become a useful source for the production of magnesite by reacting calcined dolomite with sea-water. Dolomite is a double carbonate of calium and magnesium, CaCO3, MgCO3. The mineral was first identified by Count Dolomien in 1791 and named after its discoverer. It is of sedimentary origin and is supposed to have been formed due to chemical action of sea-water containing high percentage of magnesia, on limestone. Theoretically, dolomite contains : CaCO3 : 54.35% MgCO3 : 45.65%

Feldspar is the mineral name given to a group of minerals distinguished by the presence of aluminum (Al) and the silica (SiO4) in their chemistry. They form in a variety of thermal environments, during the crystallization of liquid rock (magma), by metamorphism of rocks deep in the earth, and in sedimentary processes.

Talcum powder is a soft, white powder developed from talc, or magnesium silicate, a mineral composed primarily of magnesium, silicon and oxygen. When it is finely ground, talc absorbs moisture and helps reduce friction.
