Dolomite

The chemical composition of dolomite is CaMg (CO3) 2, which is a carbonate mineral, including iron dolomite and manganese dolomite. Its crystal structure is like calcite, often showing rhombohedron. It will slowly bubble when encountering cold dilute hydrochloric acid. Some dolomite emits orange-red light under the irradiation of cathode rays. Dolomite is the main mineral component of dolomite and dolomite limestone.
It is mainly used as a flux for alkaline refractory materials and blast furnace iron making; production of calcium magnesium phosphate fertilizer and preparation of magnesium sulfate; and ingredients for the production of glass and ceramics.
