摘要:

针对某铜钼混合精矿中次生铜含量较高且含泥量大,导致在铜钼分离浮选过程中次生铜矿物难以被抑制,产出的钼精矿不能满足质量要求等问题,进行了预先分选—铜钼分离工艺研究。结果表明:在铜钼混合精矿铜品位为24.40 %、钼品位为0.46 %及最佳的试验条件下,采用预先分选、一次粗选、两次扫选、八次精选、中矿循序返回的浮选流程,可获得钼品位51.56 %、铜品位1.05 %、钼作业回收率74.29 %的钼精矿,铜品位24.55 %、钼品位0.12 %、铜作业回收率99.97 %的铜精矿,实现了高次生铜易泥化铜钼混合精矿中铜钼的有效分离。

Abstract:

The high secondary copper and slime content in a copper-molybdenum mixed concentrate makes the secondary copper mineral difficult to inhibit during copper-molybdenum separation flotation and the produced copper-molybdenum concentrates fail to meet the quality requirement.So the pre-separation-copper and molybdenum separation process is studied.The results show that when the copper grade is 24.40 % and molybdenum grade is 0.46 % in the copper-molybdenum mixed concentrate and the test conditions are optimum,the flotation process that includes pre-separation,once roughing,twice scavenging,eight times cleaning and middling recycling,can obtain the molybdenum concentrate with copper grade 51.56 %,copper grade 1.05 % and molybdenum recovery rate 74.29 %,and the copper concentrate with copper grade 24.55 %,molybdenum grade 0.12 % and copper recovery rate 99.97 %.The new process achieves effective separation of copper and molybdenum for an easily argillizable copper-molybdenum mixed concentrate with high secondary copper content.
