Dolomite is a twofold carbonate of calcium and magnesium (CaCO3, MgCO3). It is one of the critical crude materials utilized in the iron and steel, Ferro-composites, glass, amalgam steels, the manure industry, and so on. Dolomite chips are likewise utilized in deck tiles. Dolomite is fundamentally the same as the mineral calcite.

Dolomite is an important rock-forming mineral that named is French mineralogist Déodat Gratet de Dolomieu. It is a colorless to white, pale brown, grayish, reddish, or pink mineral. Its crystals are commonly rhombohedral or tabular, often have curved faces, and sometimes cluster in saddle-shaped aggregates. Dolomite may be striated ...

Dolomite as a mineral has very few uses. However, dolostone has an enormous number of uses because it occurs in deposits that are large enough to mine. The most common use for dolostone is in the construction industry. It is crushed and sized for use as a road base material, an aggregate in concrete and asphalt, railroad ballast, rip-rap, or fill.

The mine also contains quartz, feldspar, kaolin and dolomite that are sold in Ethiopia for industrial uses. Other key minerals produced in Ethiopia include gemstones, platinum, cement, salt and gypsum, clay and shale, and soda ash.
