Dolomite was first described in 1791 as the rock by the French naturalist and geologist, DéodatGratet de Dolomieu (1750-1801) for exposures in the Dolomite Alps of northern Italy.Dolomite is the name of both a carbonate rock and a mineral consisting of calcium magnesium carbonate (CaMg(CO3)2) found in crystals. Dolomite rock (also dolostone) is composed predominantly of the mineral dolomite.

Dolomite accounts for about 10% of all sedimentary rock, including much that would have been produced near the surface of the Earth.Dolomite is a Double Carbonate of Calcium and Magnesium - CaCO3. MgCO3. It is sedimentary in origin and is supposed to have been formed due to chemical action of sea-water containing high percentage of Magnesia and Limestone.


It has high natural whiteness and its noted for their ease of dispersion.

Its use improves properties such as weathering resistance ability, reduces shrinkage, fissure development and water absorption.

Dolomite is chiefly used as Refractory, Ramming and Fettling material in Steel Melting shops, as fluxing material in blast furnace operation in secondary Steel, Fertilizers, Glass Industry, and Manufacturing of Ferromanganese. It also finds use in the manufacture of Mineral Wool & Rubber.
