1.Dolomite :CaO(31.3),MgO(21.0),SiO2(0.18) 2.size:40-80mm 3.color:white 4.packing:in bulk or ton bag  

1.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 2.8-2.9.

Our product's main use:

 1.The most common is to produce Portland cement.

 2.Producing high-grade paper coating level with heavy calcium carbonate products 3.Used for plastic, coating and other production process of packing.

 4.Production machinery manufacture of moulding sand casting with.

 5.Production desulfurization sorbent.

 6.Lime calcined and carbonization of stele inscriptions were widely used   to produce light calcium carbonate products.

 7.Used in the production of active lime and passivation lime.
