Description. Dolomite is a calcium magnesium carbonate mineral which has many characteristics similar to calcite. In places where access to limestone is not available or more costly, dolomites are used in its place for the basic materials from which most building stone and a significant percentage of crushed stone are produced.

The basic reaction, is endothermic—that is, heat must be applied to initiate and sustain it. With magnesium reaching a vapour pressure of 100 kilopascals (1 atmosphere) at 1,800 °C (3,270 °F), heat requirements can be quite high. In order to lower reaction temperatures, industrial processes operate under vacuum.
