The important application of dolomite in industrial and fertilizer production

Dolomite is the name of a carbonate sedimentary rock and is a mineral, the chemical formula of the crystals is CaMg (CO3). 2. Dolomite is slightly soluble in water, slightly soluble in dilute HCl solution, except in the form of powder.

Dolomite is used in many fields such as decorative stone; raw materials for the production of MgO; additives in fertilizer production; additives in metallurgy; production of glass, cement; production of ceramics; aquatic feed and water environment treatment in aquaculture.

Commercial dolomite is usually supplied in the form of grinding powders ranging in size from 10 micronmet to 200 micronmet depending on the application.

- Dolomite used in the metallurgical industry is mainly used in the form of heat-treated dolomite, with a CaO content of 50 ~ 56%; MgO is about 28 ~ 33%, used to make a slag for the liquid metal, protect the liquid metal from oxidation, prevent melting of the furnace wall and desulfurize the phosphorus.

- Dolomite is used in the aquaculture industry in the form of powder, about 45 micronmet size for water treatment, providing alkalinity for water, providing macronutrients and micronutrients for aquaculture.

- Dolomite is the key raw material for the mercury-producing industry with thermal heating and CaO separation by chemical or electrolytic reactions.

- Dolomite is a component used as a source of CaO in the glass and cement industries

- Dolomite is used in the fertilizer industry, as an additive for fertilizer, soil treatment for alum, alkalinity and the supply of trace elements to soil.

- Large amounts of dolomite are used in the ceramic industry.

With many applications in the industry, Dolomite is used in large quantities and is one of the most important minerals in many industries.
Green Minerals Ltd is a leading company in the field of Dolomite production and supply today.
