摘　　要：研究了羟肟酸类药剂对氟磷灰石和白云石浮选的影响。结果表明,水杨羟肟酸对氟磷灰石和白云石有一定的选择性但回收率低;辛基异羟肟酸对两者选择性差但回收率高;苯甲羟肟酸对氟磷灰石选择性和回收率都高。通过Zeta电位测试、药剂吸附量测试和XPS图谱分析研究了苯甲羟肟酸体系下氟磷灰石和白云石的浮选机理,结果表明,苯甲羟肟酸是氟磷灰石和白云石的理想捕收剂。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.
