In an experiment for Cu/Mo separation of a copper-molybdenum bulk concentrate, ozone oxidation technique was applied to enhance floatability difference between chalcopyrite and molybdenite. Under adequate ozone oxidation conditions, a molybdenum concentrate grading 47.46% Mo at 94.96% recovery, with Cu content of 0.10% can be obtained from a closed-circuit flotation test adopting a flowsheet consisting of one stage of roughing and three stages of cleaning. It is shown that the flotation indicators obtained by applying ozone oxidation technique is superior to that by using Na2S as the depressant, which indicates that the ozone oxidation technique can be used to substitute Na2S depression approach for Mo flotation whilst depressing Cu.

采用臭氧氧化法使黄铜矿和辉钼矿表面可浮性产生差异,对某铜钼混合精矿进行了铜钼分离试验研究。结果表明,在适宜臭氧氧化条件下,经过一次粗选三次精选闭路试验,可获得钼品位47.46%、钼回收率94.96%、铜含量0.10%的钼精矿。臭氧氧化浮选的指标显著高于硫化钠作抑制剂时的指标,说明可以用臭氧氧化取代硫化钠进行抑铜浮钼。

采用臭氧氧化法使黄铜矿和辉钼矿表面可浮性产生差异,对某铜钼混合精矿进行了铜钼分离试验研究。结果表明,在适宜臭氧氧化条件下,经过一次粗选三次精选闭路试验,可获得钼品位47.46%、钼回收率94.96%、铜含量0.10%的钼精矿。臭氧氧化浮选的指标显著高于硫化钠作抑制剂时的指标,说明可以用臭氧氧化取代硫化钠进行抑铜浮钼。

In an experiment for Cu/Mo separation of a copper-molybdenum bulk concentrate, ozone oxidation technique was applied to enhance floatability difference between chalcopyrite and molybdenite. Under adequate ozone oxidation conditions, a molybdenum concentrate grading 47.46% Mo at 94.96% recovery, with Cu content of 0.10% can be obtained from a closed-circuit flotation test adopting a flowsheet consisting of one stage of roughing and three stages of cleaning. It is shown that the flotation indicators obtained by applying ozone oxidation technique is superior to that by using Na2S as the depressant, which indicates that the ozone oxidation technique can be used to substitute Na2S depression approach for Mo flotation whilst depressing Cu.
