Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate and is often white, grey, pink, tan and colorless. The term dolomite is also often used for a sedimentary carbonate rock composed mostly of the mineral dolomite. Dolomite is used as a source of magnesia (a feed additive for livestock), an ingredient in the production of glass, bricks, and ceramics as well as a flux in metal processing.
