摘　　要：介绍了以新研制的氧化矿浮选的螯合型捕收剂CF为核心 ,以Pb(NO3) 2 为活化剂 ,水玻璃和六偏磷酸钠为方解石、白云石、石英、褐铁矿的选择性抑制剂的一种氧化铅锌矿物和脉石矿物浮选分离的新方法———CF法 ,并研究了该法浮选氧化铅锌矿物过程中各种因素的影响。单矿物及人工混合矿浮选试验结果表明 ,CF法在常温条件下的自然pH值矿浆中就能较好地实现氧化铅锌矿物和含钙、镁、铁、硅脉石矿物的浮选分离 ,并取得了良好的选别指标。CF法的最大特点是通过硝酸铅选择性地活化氧化铅锌矿物 ,降低CF的用量 ,且不需加温和预先用硫化钠硫化。In this paper,a new flotation method, the CF method, for separation of lead and zinc oxides from calcium,magnesium,iron and silicon minerals is introduced and the effects of a series of factors on the CF method are investigated. In this method, the collector CF, a kind of chelate collector for flotation of oxides, is taken as a core, Pb(NO 3) 2 as activator and water glass and (NaPO 3) 6 as selective depressants for calcite, dolomite,quartz and limonite. The results of flotation tests using mono mineral and mineral mixtures indicate that the flotation separation of lead and zinc oxides from calcium, magnesium, iron and silicon gangues can be effectively achieved by the CF method at room temperature and natural pH value and better flotation results obtained. The remarkable features of the CF method are that the lead and zinc oxides are selectively activated and the dosage of the CF decreased by addition of Pb(NO 3) 2 and without heating and pre-sulphidization with sodium sulphide
