Dolomite - an overview | ScienceDirect Topics

11.6.2.1 Dolomite. Dolomite is a magnesium ore with the general formula MgCO 3 ·CaCO 3. The use of dolomite as a catalyst in biomass gasification has attracted much attention (Xu, Donald, Byambajav, & 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 ...

Dolomite Value, Price, and Jewelry Information ...

What is Dolomite? A carbonate mineral, dolomite forms a series with both the very rare ankerite, in which iron (Fe) exceeds magnesium (Mg), and the manganese (Mn)-dominant kutnohorite.Dolomites that contain Fe (but not in excess of Mg) are known as ferroan dolomites. Manganoan dolomites contain Mn, of course, which gives these stones a pink color.

what are chemical sedimentary rocks - Lisbdnet.com

Chemical sedimentary rocks are formed when dissolved minerals come out of water. These rocks form in oceans, lakes, caves and hot springs and have a crystal-like shape to them. It is common to find marine life fossils in these rocks. Examples include rock salt, iron ore, limestone and flint. See also how deep is the aqueduct.

Introduction List of Most Common Carbonate Minerals

Dolomite is useful as a building stone, and crystalline dolomite forms a part of the marble of commerce. Dolomite is also used in smelting iron ore, the magnesia tending to carry the sulphur into the slag, and thus purifying the pig iron; it is sometimes used instead of common limestone in making the sulphite liquor in wood-pulp manufacture.
