subject: Dolomite Quarry Processing Plant [print this page] Dolomite is a carbonate mineral composed of calcium magnesium carbonate CaMg(CO3)2. The term is also used to describe the sedimentary carbonate rock dolostone.
Dolostone (dolomite rock) is composed predominantly of the mineral dolomite with a stoichiometric ratio of 50% or greater content of magnesium replacing calcium, often as a result of diagenesis. Limestone that is partially replaced by dolomite is referred to as dolomitic limestone, or in old U.S. geologic literature as magnesian limestone.
Uses Of Dolomite
Dolomite is used as an ornamental stone, a concrete aggregate, a source of magnesium oxide and in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper. Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smelting of iron and steel. Large quantities of processed dolomite are used in the production of float glass.
Dolomite Quarry Processing Plant
The dolomite is extracted by drilling and blasting of the quarry benches. It is then jaw crushed and screened. At this stage aggregate and feed for the lime kilns is produced. The aggregate is in single sizes from 20mm and finer. The lime kiln feed (100 to 200mm diameter) is calcined using vertical lime kilns and hydrated using either pressurised or normal hydrators (depending upon the quality of the hydrated lime required). Dolomite in the size range 20 to 30mm is crushed using a vertical impact crusher and screened to produce agricultural lime. The oversize is recirculated back into the grinding mill,If there is the demand, agricultural lime can also be produced by crushing the aggregate.
