The chemical composition of dolomite is CaMg (CO3) 2, which is a carbonate mineral, including iron dolomite and manganese dolomite. Its crystal structure is like calcite, often showing rhombohedron.
It will slowly bubble when encountering cold dilute hydrochloric acid. Some dolomite emits orange-red light under the irradiation of cathode rays. Dolomite is the main mineral component of dolomite and dolomite limestone.
It is mainly used as a flux for alkaline refractory materials and blast furnace iron making; production of calcium magnesium phosphate fertilizer and preparation of magnesium sulfate; and ingredients for the production of glass and ceramics.
Application of dolomite powder
- (1)Used for steelmaking converter lining, open hearth furnace, electric furnace wall, and secondly for thermal equipment such as furnace equipment and cement kiln.
- (2)Dolomite brick series
Dolomite with a ore size of 30-120 mm is an important material for producing magnesium metal. The smelting methods are mainly divided into two categories, namely electrolysis and silicon thermal reduction.
Production Of Magnesium Compounds
Production of magnesium carbonate, magnesium oxide, magnesium sulfate, magnesium hydroxide and other magnesium compounds
Production Of Glass
Dolomite can reduce glass aging, resist chemical corrosion, improve the plasticity of colored glass, and improve glass strength.
Production Of Ceramics
Dolomite is used in billets and glazes, and MgO and CaCO3 are introduced to replace talc and calcite, Mixing the ingredients system and then lowering the firing temperature of the body。
Production Of Painting
Used to make various pigments
Dolomite powder modified with stearic acid or stearate can improve the strength and processing properties of rubber products
Adjust Soil PH
Generally, it can increase the output value of crops by 15% to 40%, and can improve the efficacy of herbicides）
Promote animal growth and development
