dolomite Chemistry The components are CaMg(CO3)2 , Crystals Trigonal system Of Carbonate mineral 。 Dolomitic crystal Structure and calcite Similarly, the crystal form is Rhombohedron , the crystal surface is often bent into a saddle shape, Flake twin Common, mostly in massive and granular aggregates. Pure dolomite is white, because it contains other Elements and impurities sometimes appear in grayish green, grayish yellow, pink, etc, Glass Gloss. The three groups of rhombohedron have complete cleavage and are brittle. Mohs hardness 3.5-4, specific gravity 2.8-2.9. Mineral powder in cold thinning hydrochloric acid Slow reaction in.

Dolomite is a carbonate mineral Ankerite and Manganese dolomite 。 Its crystal structure is like calcite , often rhombohedral. When cold, dilute hydrochloric acid will slowly bubble out. Some dolomite Negative comparison ray It emits orange light. Dolomite is composed of Dolostone Dolomitic limestone Main minerals Composition. Dolomite can be used for building materials ceramics 、 Glass and Refractory , chemical industry, agriculture, environmental protection, energy conservation and other fields. Mainly used as Basic refractory and Blast furnace ironmaking Of flux ； production Calcium magnesium phosphate fertilizer And preparation magnesium sulphate ； And ingredients for glass and ceramics production.
