Abstract:

在乙硫氮浮选体系下,研究了小分子有机抑制剂2,3-二羟基丙基二硫代碳酸钠(SGX)对黄铜矿和方铅矿可浮性的影响,并通过动电位测试和红外光谱分析,探讨了SGX与两种矿物表面的相互作用机理.单矿物浮选试验结果表明:在整个pH值范围内,SGX对黄铜矿的浮选有一定的促进作用,而对方铅矿有强的抑制作用;随着SGX质量浓度的增加,方铅矿的回收率迅速下降,而黄铜矿的回收率有小幅度的增加.人工混合矿浮选试验结果表明,当矿浆pH值为6,SGX质量浓度为19g/L时,可得到较好的分离效果,精矿中铜的质量分数和回收率分别为2966%和8523%.动电位和红外光谱测试分析结果表明SGX与方铅矿之间的吸附能力明显强于黄铜矿.
