摘要: 针对某低品位斑岩铜钼矿矿样进行了低碱度浮选工艺研究。铜钼混合浮选阶段采用高效组合抑制剂CS,在低碱度(pH=7~8)条件下实现了铜、硫分离,伴生金属钼取得了较高的回收率;铜钼分离浮选阶段采用新型抑制剂BK510替代Na2S抑制含量较高的次生铜,在低碱度(pH=8~9)条件下取得了较好的铜钼分离效果。实验室闭路试验获得了钼品位46.21%,钼回收率84.01%的钼精矿和铜品位24.61%,铜回收率89.25%的铜精矿。

Abstract: Low alkalinity flotation process is made on a low-grade porphyry Cu-Mo ore samples.In bulk flotation stage of copper-molybdenum, high quality combining inhibitors CS were adopted to separate copper and sulfur at low alkalinity (pH=7~8), with a higher recovery rate of associated molybdenum achieved.In Cu-Mo separation flotation stage, the new inhibitor BK510 instead of Na2S was adopted to realize the inhibition of high content of secondary copper.A good Cu-Mo separation effect was achieved at low alkalinity (pH=8~9).In closed-circuit laboratory tests, molybdenum concentrate with molybdenum grade of 46.21% and recovery of 84.01%, and copper concentrate with copper grade of 24.61% and recovery of 89.25% were obtained.
