01/07/2003· Beneficiation of phosphate ores by flotation has been an important part of the concentration process since the 1920s at which time it became possible to recover those fine particles of apatite. Today, more than two-thirds of the phosphate ore produced in Florida and more than half of the world’s marketable phosphate is upgraded by the flotation method.On the Phosphate Rock Beneficiation for the Production of,,01/01/1992· For grinding phosphate rock, the energy used is about 25-35 MJ per tonne and the process water needed is around 13 m3 per tonne while the average values for ore flotation units are 62.5 MJ per tonne and 5.3 m3 per ton for energy and water use, respectively.
