Among them, granite is mostly black, white, red, and gray dotted colors, mainly composed of quartz, feldspar, and mica, commonly known as "granite".
The chemical formula of dolomite is CaCO3. Dolomite has various uses. Dolomite can be used for stone decoration and stone special-shaped carving. Dolomite powder can be used for building materials, ceramics, glass and refractory materials, chemical industry, agriculture, environmental protection, energy saving and other fields. It is mainly used as a flux for basic refractories and blast furnace ironmaking; for the production of calcium magnesium phosphate fertilizer and for the preparation of magnesium sulfate; and as an ingredient for the production of glass and ceramics. Therefore, domestic white marble is also called Baiyun marble. The dolomite with the largest storage capacity in China is located in Pinggui District, Hezhou City, Foshan. The product name is also called Foshan White Marble or Hezhou White. Pinggui District is the largest dolomite powder processing industrial park in Asia. Also called calcium carbonate powder.
Pinggui Industrial Park not only has calcium carbonate powder processing, but also dolomite marble plate processing, dolomite special-shaped processing, and artificial ecological granite industrial park.
