The effect of hydroxamic acids on flotation of fluorapatite and dolomite was studied. The flotation results show that salicylhydroxamic acid exhibits certain selectivity but low recovery for fluorapatite and dolomite; octylhydroxamic acid shows poor selectivity but high recovery for fluorapatite and dolomite; while benzohydroxamic acid possesses high selectivity and recovery for fluorapatite. The flotation mechanism of fluorapatite and dolomite in the presence of benzohydroxamic acid was studied by performing zeta potential measurement, adsorption capacity test and XPS analysis. It is found that benzohydroxamic acid is an ideal collector for fluorapatite and dolomite.
