摘要
刚果(金)SICOMINES铜钴矿区内废石铜品位为1.01%,钴品位为0.045%,具有回收价值,但该废石具有氧化率高、泥化严重等问题,为确定适宜的回收工艺流程,进行了硫化-黄药法直接浮选流程及重-浮联合流程对比实验研究。结果表明,重选-浮选联合流程指标优于硫化-黄药法直接浮选流程,可获得Cu品位为5.19%、回收率为72.82%的综合精矿,且该流程能减弱因过磨产生的泥化现象,能降低药剂消耗及磨矿能耗,用于处理该废石具有较好的经济效益及环境效益。
The copper grade of the waste rock in the Sicomines copper-cobalt mining area in Congo(DRC)is 1.01%,and the cobalt grade is 0.045%,which has the recycling value.However,the waste rock has problems of high oxidation rate and severe mudding.To determine a suitable recycling process,a comparative exploration experiment of the sulfide-yellow medicine direct flotation process and the heavy-floating combined process was carried out.The results showed that the heavy-floating combined process was superior to the sulfide-yellow medicine direct flotation process in terms of indicators,and a comprehensive concentrate with a Cu grade of 5.19%and a recovery rate of 72.82%could be achieved.The process could also reduce the mud formation caused by over-grinding,reduce reagent consumption and energy consumption,and has good comprehensive economic and environmental benefits for processing the waste rock.
