Applications

Dolomite is chosen for many construction and building product applications due to its increased hardness and density.
Asphalt and concrete applications prefer dolomite as 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
Palletization 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.
