Removed To Improve The Whiteness Of Calcite

Chemical bleaching: impurities in calcite can be oxidized into soluble substances by bleaching, and then washed and removed to improve the whiteness of calcite grinder milling plant machines.

However, the cost of chemical bleaching is relatively high, which is usually used for calcite concentrate that needs further purification after impurity removal.

Roasting purification: magnetization roasting, high-temperature roasting or chlorination roasting can be carried out by taking advantage of the differences in chemical composition and reaction activity between impurities and calcite to remove iron containing impurities, carbon containing impurities, sulfide and other impurities in calcite.
