Properties of Dolomite. Dolomite is a calcium magnesium carbonate with a chemical composition of CaMg(CO 3) 2. Limestone that contains some dolomite is known as dolomitic limestone. Uses Of Dolomite. Dolomite is chosen for many construction and building product applications due to its hardness and density. A few applications …
The steel industry uses dolomite as a sintering agent in processing iron ore and as a flux in the production of steel. In agriculture, dolomite is used as a soil conditioner and as a feed additive for livestock. Dolomite is used in the production of glass and ceramics. Dolomite has been used as a minor source of magnesium, but today most ...
Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate. Along with calcite and aragonite, dolomite …
