| 摘 要： | 本文以湖北某磁选尾矿中铜的综合回收为研究对象，通过工艺矿物学研究表明，该磁选尾矿组分较为复杂，铜含量较低为0.38%，嵌布粒度较细，铜主要赋存于原生硫化铜中，分布率为74.08%，铜矿物主要是黄铜矿，少量铜蓝、辉铜矿等，脉石矿物主要是石英，其次为方解石、白云石、绢云母，少量长石、高岭石等。针对尾矿中铜矿物“贫、细、杂”的特点，采用CCF浮选柱进行回收铜的选矿实验研究，研究结果表明，经过一次粗选一次扫选和两次精选作业，可从含铜0.38%的尾矿中获得铜品位16%以上，铜回收率76% 以上的铜精矿，实验指标良好，实现矿产资源综合回收利用。

| Abstract: | In this paper, the comprehensive recovery of copper from a magnetic separation tailings in Hubei Province is studied. The process mineralogical study shows that the composition of the tailings is relatively complex, with low copper content of 0.38% and fine disseminated particle size. Copper mainly occurs in primary copper sulfide, with a distribution rate of 74.08%. The copper ore is mainly chalcopyrite, a small amount of copper blue, chalcocite, etc., and the gangue mineral is mainly quartz, the second is calcite, dolomite, sericite, a small amount of feldspar, kaolinite and so on. According to the characteristics of "poor, fine and miscellaneous" copper minerals in tailings, the CCF flotation column was used to carry out the beneficiation test of recovering copper. The results show that after one roughing, one scavenging and two cleaning operations, the copper concentrate with copper grade of more than 16% and copper recovery of more than 76% can be obtained from the tailings containing 0.38% copper. The test index is good, and the comprehensive recovery and utilization of mineral resources can be realized. |
