Dolomite is a carbonate mineral composed of calcium magnesium carbonate. A very common mineral and is best known for its saddle shaped curved crystal aggregate. Today Dolomite does not form on the surface of the earth, yet massive layers of Dolomite can be found in ancient rocks. These rocks are called appropriately enough Dolomite or dolomite limestone. It is of sedimentary origin and is supposed to have been formed due to chemical action of seas water containing high percentage of magnesia, on limestone. 

Dolomite usually contains impurities, chiefly silica, alumina and iron oxide. For Commercial purposes, the percentage of combinedimpurities should not go beyond 7% above which, it becomes unsuitable for industrial use. It is then used for raod ballasts, building stones, florring chips etc.

Dolomite is a double caronate of calcium and magenium , 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 checmical action of seas water containing high percentage of magnesia, on limestone.

Dolomite Contains : 

CaO - 30.4%

MgO - 21.7%

CO2  - 47.9%

1) It is manly used for refactory, ramming and fettling material in steel melting industries and as fluxing material in blast furnance operation in secondry steel and ferromanganese manufacture. Also used especially in sheet glass manufacture.

2) Also used for many construction and building product applications due to its inceresed hardnes and density.

1) Widely used as a substitute for limestone.

2) Soil Conditioner

3) Achieves high bulk density

4) Commonly used by refactory and flux industries

5) Used as an agent for float glass production.
