Dolomite Powder Supplier and Exporters in India
By combining calcined dolomite and seawater in England, dolomite has proven to be an effective source for the production of magnesite.
Dolomite is a type of double carbonate rock that contains calcium and magnesium in variable proportions depending on the mining zone. Dolomite is more chemically inert and resistant to acid attack than the calcite form of calcium carbonate or limestone. It is also harder and denser. It is chemically and physically similar to calcite, but with half as many magnesium ions.
