  • Recovery of Apatite From Ore Slimes Using Centrifugal

    The aim of this study is to determine the feasibility of using a centrifugal heavy medium separation (CHMS) method to obtain apatite concentrates from ore slimes (particle size < 45 µm 4.5% P2O5). The effects of the specific gravity centrifugal speed and time on the P2O5 content of the product and its recovery were investigated based on the Box–Behnken approach.
