Dolomite: Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth's crust. Learn more about the structure, properties, and uses of dolomite in this article.
Woodward Iron Company Four iron-making enterprises, each controlling substantial deposits of iron ore, coal, limestone and dolomite, came to dominate the industry. These companies were unique in their use of advanced blast-furnace plants that smelted iron ore into pig iron.
Dolomite can also serve as a host rock for lead, zinc, and copper deposits. In the chemical industry, dolomite is used as a source of magnesia (MgO). The steel industry uses dolomite as a sintering agent in processing iron ore and as a flux in the production of steel.
