摘要: 为了研制铜铅矿物浮选分离的高效铅抑制剂,以黄铜矿、方铅矿单矿物在CMC、硫酸铝或二者组合抑制体系中的可浮性特征为基础,研究了硫酸铝+CMC在郴州某铜铅混合精矿浮选分离中的抑铅浮铜效果,最后分析了硫酸铝影响Z-200在黄铜矿、方铅矿表面吸附的机理。结果表明:CMC、硫酸铝以及硫酸铝+CMC均可增大黄铜矿和方铅矿的可浮性差异;在先添加硫酸铝后添加CMC的情况下可低成本、小污染、高效率地实现铜铅混合精矿的分离。因此,硫酸铝+CMC是铜铅浮选分离的新型铅抑制剂。

Abstract: Based on floatability characteristic of chalcopyrite and galena in CMC,aluminum sulfate or these two combined suppression system,effect of lead inhibition and copper flotation by aluminum sulfate+CMC in flotation process of a Cu-Pb mixed concentrate from Binzhou was studied. And then,the influence of aluminum sulfate to the absorption of Z-200 on the surface of chalcopyrite and galena was analyzed. The results showed that CMC,aluminum sulfate and these two combined reagents all increased the floatable difference of chalcopyrite and galena. The separation of copper-lead mixed concentrate can be realized with lower cost,less pollution and higher efficiency by firstly adding aluminum sulfate and then CMC. Hence,aluminum sulfate+CMC is recommended as new-type Pb depressant in copper-lead separation.
