Information about Dolomite

Rocks are naturally occurring solids which are composed of minerals & have been used by humans since ages. From Stone Age, rocks are used for various purposes. Also, the metals and minerals found in rock play an important role in our life. Get to know all the Dolomite Uses. We have provided you with all information about Dolomite rock here. Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight. Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dolomite is white.

Characteristics of Dolomite

Many rocks have distinct characteristics. Some of the Properties of Dolomite are hardness, structure, streak, fracture etc. Dolomite is significant as it is composed of minerals and has variety of uses in our day to day life. The characteristics of Dolomite plays an important role in its identification. The hardness of Dolomite is 3.5-4 on Moh’s hardness scale. Rocks according to their hardness are divided into:Hard Rocks, Soft Rocks and Rocks with Medium Hardness. Fracture of Dolomite rock is conchoidal. Its specific heat capacity is 0.92 kJ/Kg K. Dolomite is heat resistant, pressure resistant, wear resistant. Some of its uses are:

  • Interior Uses: Decorative aggregates, Homes and Interior decoration.
  • Construction Industry: As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics, Serves as an oil and gas reservoir rock.
