Construction Materials: Dolomite & Metallurgical Dolomite

Dolomite can be defined as a Calcium-Magnesium-Carbonate (formula CaMg(CO3)2), which is utilized extensively in metallurgical applications, and as a construction aggregate.

Metallurgical grade dolomite, with less than 3% silica content (SiO2), is a source of magnesium ore (MgO) utilized as a fluxing agent in iron and steel making, and ferrochrome production.

As a construction aggregate, dolomite has an impressively low water demand, allowing for cement savings in concrete applications. It is also used as a road base material, an aggregate in concrete and asphalt, a railroad ballast, fill-material, and in the production of bricks, blocks, and lintels, etc.
