Feb 22, 2019 Dolomite is a magnesium ore with general formula MgCO3. CaCO3 . What mineral is formed from dolomite? Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO3)2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite….Introduction
Dolomite is a very common mineral, and is known for its saddle-shaped curved crystal aggregates. A unique, isolated Dolomite occurrence in Eugui, Spain has provided colorless transparent crystals that resemble the Iceland Spar variety of Calcite.The occurrence of Kolwezi, in the Congo, has produced some fascinating, cobalt-rich specimens that are a beautiful hot pink color and highly popular

Dolomite is a double carbonate of calium and magnesium, CaCO 3, MgCO 3. ... Dolomite has been found as a useful support to limestone in removing sulphur from the iron ore. It also reduces the viscosity of the slag, thus chemical reactions in the furnace. For the steel melting shop the total insolubles below 4% are preferred

3.1. Characterization of dolomite ore The chemical analysis of New-Valley dolomite ore is given in Table 1. It is clear that, the theoretical MgO content in pure dolomite mineral is 21.875%, this indicates that, the purity of dolomite ore is about 75.66%. The ore contains a high amount of calcium oxide which causes the problems after solid/liquid

May 04, 2019 The ore host rock is traditionally assigned to the dolomite marble unit H8, which is overlain by H9 K-rich slate. The Bayan Obo deposit is located at the center of the Kuangou syncline, which consists of several chevron folds, shear zones, and thrust faults (Yang et al. 2017).The deposit is exploited in three open pits, the Main, Eastern, and Western, which host predominantly Fe reserve
