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.
t is a chemical element in the periodic table, expressed by the symbol Mn, and its atomic number 25. It is found in nature as an element (often with iron) or in other minerals. If it is a free element, it is of great importance in the field of industry, especially in the steel industry. Manganese use: 1- Iron alloy with manganese is used in the manufacture of railways. 2- It is used in making dry column. 3- Manganese sulfate is used as a fungicide. 4- It is used in making ferromanganese alloy and hard alloys. 5- Refractory industry. 6- It is used in chemical industries. 7- It is used in building materials industry.
