Limestone is a common type of carbonate sedimentary rock. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate. Limestone forms when these minerals precipitate out of water containing dissolved calcium

Dolomite is a carbonate mineral, including ankerite and manganese dolomite. Its crystal structure is like calcite and is often rhombohedral. It will bubble slowly when exposed to cold dilute hydrochloric acid. Some dolomite emits orange light under cathode ray irradiation. Dolomite is the main mineral composition of dolomite and dolomitic limestone. Dolomite can be used in building materials, ceramics, glass and refractory materials, chemical industry, agriculture, environmental protection, energy conservation and other fields. It is mainly used as flux for basic refractory and blast furnace ironmaking. Production of calcium magnesium phosphate fertilizer and preparation of magnesium sulfate; As well as ingredients for producing glass and ceramics.

Dolomite powder is used as a raw material for the production of high-grade glassware, medicine bottles and optical glass. Dolomite powder has limited dosage in paints, confined to be used as filler, mainly playing the role of white pigment. However, due to the coarse particles, refractive index and paint solvent similar to the covering power is weak, there is no certain special role in the application, just for the body pigment filler paint.- Used in the building materials and refractory materials, chemical and agricultural, environmental protection, energy conservation and other fields. - Used in the production of glass and ceramic ingredients; - Used as refractory inner layer, slag making agent, cement raw material, glass flux, kiln industry, building and decoration stone material, paint;
