dolomite | Formation, Structure, Properties, Uses, amp; Facts
Dolomite, also known as calcium magnesium carbonate, is a nonmetallic material used in manufacturing bricks, mortar, cement, concrete, plastics, paving materials, and other construction materials.
Dolomite is a magnesium ore with the general formula MgCO 3 #183;CaCO 3. The use of dolomite as a catalyst in biomass gasification has attracted much attention (Xu, Donald, Byambajav, amp; Ohtsuka, 2010). The chemical composition of dolomite varies from source to source, but it generally contains 30 wt.% CaO, 21 wt.% MgO, and 45 wt.% CO 2.
#0183;#32;Dolomite types On the basis of the mode of formation, dolomites can broadly be divided into two groups: primary dolomite and secondary Primary dolomite precipitate directly from aqueous solution, mostly at or near room temperature (2035oC), with no CaCO 3 dissolution However, dolomite can also form as a secondary phase
Rocks normally consist of several minerals, some essential, some accessory. A rock may be thought of as a quot;mineral environment.quot; Each rock type was formed under certain specific conditions, resulting in the formation of a fairly predictable group of minerals. Rocks fall into three classes according to their origin: Igneous, Sedimentary, Metamorphic.
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
Dolomite differs from calcite and aragonite in its crystal structure. In dolomite Few dolostones are primary in origin. By volume, the most important uses of dolomite are in the production of concrete and as aggregate construction material. Read more
Dolomite can often contain sodium, but it should only be percent sodium or less. More sodium can change the salinity of your soil, which can kill many plants. Why Use Dolomite
Dolomite, also known as quot;dolostonequot; and quot;dolomite rock,quot; is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesiumrich groundwater. Dolomite and limestone are very similar rocks.

Damage to structures and loss of life have been more severe on dolomite than on any other geological formation in southern Africa. The subsidence that occurs on dolomitic terrain following development or during dewatering has given dolomite a notorious reputation and engineers and geologists became reluctant to recommend development on the material.
Abstract The origin of largescale ancient dolomite is one of the most hotly debated topics in sedimentology. The Loushanguan group of the upper 3rdFurongian Cambrian series on the southeastern m...
Dolomite carbonatites are of the same general origin as calcite carbonatites. The dolomite present in dolomite veins has also been ascribed diverse origins; some appears to have been deposited by percolating connate or meteoric groundwater, and some seems more likely to have been deposited by hydrothermal solutions charged with magmatic volatiles.

#0183;#32;FACTS ABOUT DOLOMITE. Dolomite is a type of limestone used to manufacture magnesium salts. It is coined after a French mineralogist, Deodat de Dolomieu. Very rare pink varieties of dolomite are found in Congo, Africa. It is used in the medical industry as a laxative to make magnesia.
The uses of Dolomite in construction industry include 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 and that of Quartzite
The history and origin of the Dolomites in a nutshell. It is difficult to imagine that herbivorous dinosaurs of up to three meters in size cavorted around 280 million years ago before their habitat was swallowed up by the sea which took a total of 200 million years, mind you, where today there are colourful meadows and proud mountaintops that invite you to go hiking, biking or skiing.
The use of dolomite in the construction industry Aggregates are very common in many applications, including the building of houses, use as a base layer for asphaltpaved roads, and in concrete and asphalt manufacturing technologies. Aggregates are an excellent decoration for yards and gardens.
