中文摘要: 刚果(金)SICOMINES铜钴矿属于高氧化率难选铜钴矿,使用浮选-磁选联合工艺处理该矿石,其磁选精矿品位低,产率较大,磁选精矿直接浸出经济效益差。为提高该铜钴矿磁选精矿铜钴选冶综合效益,对磁选精矿进行再磨再选处理,采用硫氢化钠作为硫化剂,黄药作为捕收剂,2#油作为起泡剂,进行了磁选精矿再磨再选试验研究,在最佳条件下,可获得产率18.48%、铜品位3.84%、钴品位0.36%、铜回收率56.15%、钴回收率35.20%的精矿,且精矿铜浸出率可达到85.64%,钴的浸出率可达到74.05%,吨铜净酸耗为2.15t/t铜,获得较好的经济效益。
Abstract:In order to improve the recovery rate of copper and cobalt in the magnetic separation concentrate of Congo (Kinshasa) SICOMINES Copper-Cobalt mine , in view of the low copper-cobalt grade in the magnetic separation concentrate and the poor enrichment effect of magnetic separation. In order to improve the comprehensive benefits of copper-cobalt ore magnetic separation concentrate copper-cobalt metallurgy, the magnetic separation concentrate was remilled and re-selected, sodium hydrosulfide was used as vulcanizing agent, yellow medicine as collector, 2# oil as foaming agent, magnetic separation concentrate regrinding and re-selection test research was carried out, under the best conditions, concentrate with yield of 18.48%, copper grade of 3.84%, cobalt grade of 0.36%, copper recovery rate of 56.15%, cobalt recovery rate of 35.20%, and the copper leaching rate of concentrate can reach 85.64%. The leaching rate of cobalt can reach 74.05%, and the net acid consumption of copper per ton is 2.15t/t copper, which obtains good economic benefits.
