Characteristics of Dolomite

Dolomite is a carbonate mineral, respectively with manganese iron dolomite and dolomite. Its crystal structure like calcite, often assumes the rhombohedron. Slowly out of the bubble when they encounter cold dilute hydrochloric acid. Dolomite of trigonal system, chemical composition of CaMg(CO3)2, is mainly composed of calcium carbonate and magnesium carbonate minerals (CaCO3 and MgCO3 roughly the proportion of 1:1), complete with cleavage and ling surface crystallization. Color is white, gray, incarnadine, colorless, green, brown, black, dark pink, transparent to translucent, with vitreous luster, hardness is 3.5 4, the proportion of 2.85 to 2.9.

Application of Dolomite

Conversion of dolomite can be used in steelmaking furnace refractory lining, slagging agent, flux cement raw material, glass, ceramic industry, fertilizer, construction and decorative stone, paint, pesticides and medicine and other purposes. Can be used in building materials, ceramics, glass and refractory materials, chemical industry and agriculture, environmental protection, energy saving, etc. As well as the production of glass and ceramics ingredients. Also can match into the embryo glaze as fluxing agent. Some ancient kiln in the north field, such as kiln often add dolomite in embryo glaze, jingdezhen also join in some of the glaze of dolomite.

Related research of Dolomite

Dolomite rock often symbiosis with reservoir not only, more is in close relationship with salt or metal ore deposits and the formation of dolomite are still controversial, the focus for magnesium 2 + the source of the problems in the process of dolomitization. Dolomitization is closely related with basin deep activities, usually controlled by deep hot fluid activity; The dolomitization is the development of the basin, the deep are widespread in a crust – high conductivity layer at low speed. According to the fluid inclusions homogenization temperature data, found that dolomite formation of the environment temperature is higher than that of calcite, and often much higher than normal formation temperature.
