      The beneficiation of apatite from low grade magnetite-apatite ore was studied. Wet magnetic separation followed by flotation was found effective. The effects of different grinds, pH, depressants and collectors at varying dosages were investigated. Various process parameters were optimized and the rougher concentrate was cleaned thrice for improvement in the apatite grade. Sodium silicate as depressant, sodium oleate as collector and pine oil as frother, at a pH of 7–7·5 (natural pH), for apatite flotation were found effective. The general flowsheet of the process was developed.
