Applications:

(MAINLY USE FOR GLASS INDUSTRY)

1.Glass industry: white ash stone and dolomite are important ingredients in glass raw materials, which can play the role of flux, which can greatly reduce glass aging, reduce the plasticity of colored glass, and further improve the strength of glass.

2. Chemical field: production of magnesium sulfate, magnesium oxide, light magnesium carbonate, sand, rubber and plastic fillers;

3. Building materials industry: It can produce sulfate magnesia cement, high performance magnesia chloride cement, burnt lime silicate brick, and handle cracks of gypsum products and wood products.

4. Ceramic industry: In the blank and glaze of ceramics, dolomite is used to introduce magnesium oxide and calcium carbonate components to replace talc and calcite;

5. Environmental protection: water treated dolomite can be used as filter material, which is very useful in drinking water, industrial water, swimming pool water and other fields;

6.Metallurgical refractories: as a magnesia slagging agent in steel smelting, to combine fused silicon, aluminum, sulfur, phosphorus and other unwanted or harmful associated elements, can extract magnesium metal, steelmaking refractory materials;
