铜、钼浮选分离探索试验研究

对某大型铜钼矿的铜钼混合精矿进行了铜、钼分离浮选试验研究。试验结果表明：硫化钠加高锰酸钾能够有效地抑制铜矿物,钼精矿中的铜的含量有较大幅度的下降,并且能够在不添加巯基乙酸钠的条件下使铜、钼得到很好的分离,并取得了铜、钼品位分别为27.06%、45.28%和作业回收率分别为99.90%和95.23%的较好指标。

Exploratory research on copper and molybdenum mixed concentrate separation floatation

Experimental researches are carried out on copper and molybdenum mixed concentrate separation floatation in a big copper-molybdenum mine. Researches show that NaES and KMnO4 can effieciently depress copper minerals. So copper content in molybdenum concentrate decreases obviously and they can be separated without adding sodium thioglycolate. The final grade of copper and molybdenum concentrate is 27.06 % and 45.28 % respectively; the recovery rate is 99.90 % and 95.23 % respectively.
