Mining and Beneficiation of Phosphate Ore IntechOpen

The removal of carbonates from phosphate rock has been the focus of significant research efforts. Several countries have large deposits of phosphate rock that contain significant amounts of calcite (CaCO 3) and dolomite (CaMg(CO 3) 2). The calcination of phosphate ores to remove carbonates is expensive because of high costs of energy.
