Description

Chemical composition of dolomite is CaMg[CO3]2, the crystal is the trigonal system carbonate minerals. The crystal structure and the calcite are similar, and the crystal form is the rhombohedra, the crystal face is often curving becomes saddle, with common polyflake and macle, assumes block or granular aggregation. 2. The purity is white with glassy luster. Dolomite is used as the ingredient of metallize flux, refractory material, building material, glass and ceramic. Hardness is 3.5 - 4, specific gravity is 2.**2.9.
