Dolomite - WikipediaThe mineral dolomite crystallizes in the trigonal-rhombohedral system. It forms white, tan, gray, or pink crystals. Dolomite is a double carbonate, having an alternating structural arrangement of calcium and magnesium ions. It does not rapidly dissolve or effervesce (fizz) in dilute hydrochloric acid as calcite does.what do they mine in the dolimite,Information on Magnesite, Dolomite and Magnesium Mining in.Information on Magnesite, Dolomite and Magnesium Mining in Europe?

Can you provide information on the mining of Magnesite, Dolomite, Serpentine and the processing of such ores and.
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.

Hardness is 3.5 to 4.5 and the specific gravity varies from 3 to 3.2. A vitreous lustre and very slow reaction with cold acids distinguishes magnesite from other carbonates. Magnesite, dolomite, sea water and lake brines are used as sources of magnesium metal with the most common source being lake brines and sea water.
