Report on Abu Tartur Phosphate Rock Beneficiation
The beneficiation of phosphate rock can often be simplified and made more economic by taking into account the distribution of P2O5 and impurities as a function of their deportment between the size fractions resulting from mined and comminuted sedimentary phosphates. A number of case studies developed by TBT are presented in the current paper.
