| 摘 要： | 中色卢安夏铜业有限公司(CLM)巴卢巴选矿厂浮选混合精矿中含有0.8%～1.2%的钴,若能从铜精矿中分离出钴精矿,则可以获得较好的经济效益。CLM公司拟利用巴卢巴选矿厂技改工程的新建浮选系统及原有浮选系统生产铜、钴精矿。通过铜钴分离试验,确定了混合精矿分离工艺,得到的铜精矿含铜25.44%、含钴0.17%、铜回收率为87.83%,钴精矿含钴1.48%、钴回收率为67.65%、含铜2.23%,获得了较好的选矿技术经济指标。

| Abstract: | The cobalt grade in bulk concentrate produced at CNMC Luanshya Copper Mine PLC is in the range of 0.8% ～1.2%.According to the market demand,a better economic benefit can be obtained when copper and cobalt are produced as separate concentrates.According to this plan,the two concentrates will be produced using initial flotation system and new flotation system.The separation tests show that the copper grade and the cobalt grade is 25.44% and 0.17% respectively in copper concentrate with a copper recovery of 87.83%.In the cobalt concentrate,the copper grade is 2.23% and the cobalt grade is 1.48% with a cobalt recovery of 67.65%.With this process,good financial and metallurgical indexes can be achieved. |
