摘要: 针对新疆某低品位铜镍矿矿石性质的特点,采用1粗2扫2精铜镍混浮、1粗1扫铜镍分离、中矿顺序返回的闭路试验流程,铜镍混浮以CMC与水玻璃的组合为脉石矿物抑制剂、异丁基黄药为捕收剂、A8为辅助捕收剂,铜镍分离以活性炭为脱药剂、石灰与T12的组合为镍矿物抑制剂、Z-200为捕收剂,获得了铜品位为27.03%、铜回收率为67.79%、含镍0.93%的铜精矿,以及铜品位为3.79%、镍品位为5.59%、铜回收率29.14%、镍回收率70.82%的铜镍混合精矿。

Abstract: According to the characteristics of the low grade copper-nickel ore in Xinjiang,adopt a closed circuit test flowsheet which have one roughing,two scavenging and two concentrating copper-nickel mixed floating;and one roughing,one scavenging copper-nickel separation,middlings order returned.Reagents used in copper-nickel mixed flotation are the combined depressants of CMC and Sodium silicate,collecter iso-butyle Xanthate and assistant collecter A8. Copper-nickel separation medicament is conducted: using Activated Carbon to remove reagents,lime and T12 as the Inhibitors,Z-200 for collector.The Copper concentrate is obtained with Copper grade of 27.03%,nickel grade of 0.93% and Copper recovery of 67.79%. the mixed concentrate of copper and nickel is obtained with nickel grade of 5.59%,copper grade of 3.79% and nickel recovery of 70.82%,copper recovery of 29.14%.
