dolomite sand 80-120 mesh

Dolomite sand (snow white) 80-120 mesh, chemical composition is CaMg (CO3) 2, crystal belongs to the carbonate mineral of cubic system. The crystal structure of dolomite is similar to that of calcite. The crystal form is rhombohedron, and the crystal surface is often bent into saddle shape. Flake twin crystals are common, and they are mostly massive and granular aggregates. The pure dolomite is white, sometimes gray green, gray yellow, pink and other colors due to other elements and impurities, with glass luster. Three groups of rhombohedron cleavage complete, brittle. The hardness is 3.5-4 and the specific gravity is 2.8-2.9. The reaction of mineral powder in cold dilute hydrochloric acid is slow.

Dolomite can be used as refractory lining, slagging agent, cement raw material, glass flux, kiln, fertilizer, building and decoration stone, paint, insecticide and medicine of converter furnace. It can be used in building materials, ceramics, glass and refractory, chemical
