DOLOMITE MINERAL
1 MM Dolomite Mineral Dolomite is also a common mineral in hydro-thermal veins. There it is often associated with barite, fluorite, pyrite, chalcopyrite, galena, or sphalerite. In these veins it often occurs as rhombohedra crystals which sometimes have curved faces.
â??Dolomite mineralâ?? is a word that is used by geologists in two different way
1) as the name of the mineral dolomite
2) as the name of a rock known as dolomite, dolostone or dolomite rock.
Dolomite Mineral originates in the same sedimentary environments as limestone i.e. in warm, shallow, marine environments where calcium carbonate (CaCO3) mud accumulates in the form of shell debris, fecal material, coral fragments, and carbonate precipitates. Dolomite is thought to form when the calcite in carbonate mud or limestone is modified by magnesium-rich groundwater. The available magnesium facilitates the conversion of calcite into dolomite.
Uses of dolomite mineral
It is being used as construction material, in agriculture and in industry. In industry it is being used
(i) as a fluxing material (ii) as a refractory material (iii) as a filler material.
The major industries where dolomite mineral is being used are iron and steel industry, Ferro alloy industry, plastic industry, ceramic industry, glass industry, fertilizer industry, and soap and detergent industry etc.
In the chemical industry, dolomite is used as a source of MgO. In agriculture, dolomite is used as a soil conditioner and as a feed additive for livestock.

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO3)2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone. Most rocks that are rich in dolomite were originally deposited as calcium carbonate muds that were postpositionally altered by magnesium rich pore water to form dolomite. Dolomite is also a common mineral in hydrothermal veins. That may have barite, galena, fluorite, etc. Dolomite crystals are colorless, white, buff-colored, pinkish, or bluish. Granular dolomite in rocks tends to be light to dark gray, tan, or white. Dolomite long has been used as a source of calcium and magnesium for animal feeds. It is now available in a number of dosage forms including tablets and chewable wafers, to be taken as dietary supplements. Dolomite is used as a source of magnesia (MgO), a feed additive for livestock, a sintering agent and flux in metal processing, and as an ingredient in the production of glass, bricks, and ceramics. Dolomite is used as a source of magnesium metal and of magnesia (MgO), which is a constituent of refractory bricks. Dolomite serves as the host rock for many lead, zinc, and copper deposits. Dolomite also serves as an oil and gas reservoir rock. This can produce pore spaces in the rock that can be filled with oil or natural gas that migrate in as they are released from other rock units. This makes the dolomite a reservoir rock and a target of oil and gas drilling. Agriculture grade dolomite used for soil neutralization and conditioner to correct acidity. It also finds use as filler in fertilizers. The main ingredient is calcium carbonate, it helps to increase the pH of acidic soils and it provides a good source of calcium for plant. It improves the water penetration for acidic soil.

Dolomite is rarely found in modern sedimentary environments, but dolostones are very common in the rock record. They can be geographically extensive and hundreds to thousands of feet thick. Most rocks that are rich in dolomite were originally deposited as calcium carbonate muds that were postdepositionally altered by magnesium-rich pore water to form dolomite.

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. It is also calcined in the production of cement and cut into blocks of specific size known as "dimension stone."
Dolomite's reaction with acid also makes it useful. It is used for acid neutralization in the chemical industry, in stream restoration projects, and as a soil conditioner.

Dolomite serves as the host rock for many lead, zinc, and copper deposits. These deposits form when hot, acidic hydrothermal solutions move upward from depth through a fracture system that encounters a dolomitic rock unit. These solutions react with the dolomite, which causes a drop in pH that triggers the precipitation of metals from solution.
Dolomite also serves as an oil and gas reservoir rock. During the conversion of calcite to dolomite, a volume reduction occurs. This can produce pore spaces in the rock that can be filled with oil or natural gas that migrate in as they are released from other rock units. This makes the dolomite a reservoir rock and a target of oil and gas drilling.
