Uses. Dolomite is used as a source of magnesium metal and of magnesia (MgO), which is a constituent of refractory bricks. Dolostone is often used instead of limestone as an aggregate for both cement and bitumen mixes and also as a flux in blast furnaces. The use of dolostone as a flux has increased, especially since environmental contamination ...

A fluctuating solution to the dolomite problem | Science
Dolomite is a mineral very similar to calcite, the calcium carbonate that forms the shells of many foraminifera, mollusks, and bivalves whose accumulation at the bottom of the seas created the well-known limestones. The difference between dolomite and calcite is that the former contains equal parts calcium and magnesium.
Dolomite
Dolomite. Dolomite is, after calcite, the second most important and abundant of the carbonate minerals.
