Dolomite is Carbonate of Calcium and Magnesium Ca Mg (CO3)2 Chemical Analysis of Dolomite Powder:-
Calcium Oxide (Cao)            (30 +/- 2%)
Magnesium Oxide (Mgo)      20 (+/- 2%)

Uses For Dolomite

The inherent differences between dolomite and calcite drive the applications for dolomite. Dolomite is chosen for many construction and building product applications due to its increased hardness and density. Asphalt and concrete applications prefer dolomite as a filler for its higher strength and hardness. Dolomite also finds use in a number of applications as a source of magnesium such as glass and ceramics manufacture, as well as a sintering agent in iron ore pelletization and as a flux agent in steel making. Farmers use dolomite for agricultural pH control. The chemical industry uses the mineral dolomite in making magnesium salts including magnesia, magnesium oxide (MgO), which is used in pharmaceuticals.

Dolomite is widely used in Iron & Steel Industries due to its strength and compatibility in process of purifiying Iron & Steel.

As an industrial mineral, dolomite’s usage is significantly less than calcite’s. This is primarily due to the relative lack of high brightness deposits of dolomite. The alteration process that forms dolomite tends to bring in additional impurities that reduce brightness or tint the stone brown or gray. In regions where high brightness dolomites do exist, they share many of the applications of calcium carbonate.

The dolomite can be used in building materials, porcelain, glass and refractory after dolomite crushing. In chemical industry, agriculture, environmental protection, energy conservation etc.


Application in metallurgical industry: In the metallurgical industry, dolomites are mainly used as flux, refractories, refining of metal magnesium and magnesium compounds after dolomite mining.

The usage in building materials industry: Calcined dolomite can be processed to make dolomitic limestone which is of good White, strong adhesion, coagulation power, Fire-resistant, heat insulation. In these stages, dolomite crusher equipments are needed. Therefore the dolomite is suitable for Interior and exterior wall coating. The calcined dolomite can be used in Magnesium chloride cement and concrete curing. After adding other brasque, they can be used for flooring. What’s more, the dolomites can be directly used as building materials. There are many dolomite crushing machines which can help broad dolomite application in dolomite mining or quarrying.

Application in chemical industry: In chemical industry, the dolomite is mainly used to produce chemicals, such as Magnesium sulfate, Light magnesium carbonate, etc. Dolomite crusher can crush the stone to required fineness which is suitable to production. Apart from all these above, the crushed dolomite powder has been widely applied in agriculture, filler, etc. After dolomite mining and crushing, we can use it to make more products which are often used in various of industries.
