Activation effect of Pb2+ in cassiterite flotation with styrene phosphonic acid as collector

  • 摘要: 通过单矿物浮选试验揭示了Pb2+对苯乙烯膦酸(SPA)浮选锡石效果的影响规律,在此基础上,利用接触角测定、Zeta电位检测、红外光谱分析和浮选溶液化学研究了苯乙烯膦酸浮选锡石体系中Pb2+的活化作用机理.单矿物试验结果表明:在矿浆pH为2.0~8.0的区间内Pb2+对锡石的浮选具有明显的活化作用,矿浆pH为4.0时锡石的回收率最高,达到93.78%,与不存在Pb2+的情况相比提高了5.33%.Zeta电位检测、红外光谱分析和浮选溶液化学结果表明:苯乙烯膦酸主要化学吸附于锡石表面,使锡石表面的Zeta电位负移,Pb2+的作用促进了苯乙烯膦酸的吸附,进一步降低了锡石表面的Zeta电位;Pb2+可以与锡石表面的Sn4+发生置换,PbOH+能够与锡石表面的Sn-OH发生相互作用形成以Sn-O-Pb+形式存在的络合物,这些作用增加了锡石表面的活性位点数量,使得苯乙烯膦酸在锡石表面的吸附量增多,导致了锡石的活化.
