ABSTRACT:
A method is disclosed for beneficiating a phosphate ore matrix containing apatite, siliceous gangue, and an alkaline earth metal carbonate mineral impuritywhich includes the steps of washing and sizing the ore, subjecting it to a gravity separation, a conventional "double float" flotation, and a phosphate-carbonate flotation separation to provide a phosphate ore concentrate having a high BPL content and a relatively low concentration of alkaline earth metal carbonate mineral impurity.
