广东某硫化铜矿石工艺矿物学及分选工艺研究

为了提高广东某低品位硫化铜多金属矿中铜以及共伴生硫、铁的资源利用率，采用化

学多元素分析、矿物自动分析仪等手段进行了系统的工艺矿物学研究。结果表明，矿石中 Cu、S、Fe

的含量分别为 0.50%，27.68%，34.07%。黄铜矿为铜的主要赋存矿物，其他含铜矿物有铜蓝、辉铜矿

等。针对铜硫分离困难的问题，提出采用半自磨—球磨—铜浮选—磁黄铁矿磁选—硫浮选的流程，

可以获得铜精矿铜品位为16%，回收率为70%，磁选后磁黄铁矿精矿硫品位为30%，回收率为36%，硫

精矿硫品位为40%，回收率为45%的结果，获得了较好的铜硫分离效果。

In order to improve the resource utilization rate of copper and associated sulfur and iron in a

low-grade copper sulfide polymetallic ore in Guangdong，a systematic process mineralogy study is carried

out by means of chemical multi-element analysis and mineral automatic analyzer. The results show that the

contents of Cu，S and Fe in the ore are 0.50%，27.68% and 34.07%，respectively. Chalcopyrite is the main

occurrence mineral of copper，and other copper-bearing minerals include covellite，chalcocite，etc. Aiming

at the problems of difficult separation of copper and sulfur，a process of semi-autogenous grinding-ball mill⁃

ing-copper flotation-pyrrhotite magnetic separation-sulfur flotation is proposed. Indexesof copper concen⁃

trate with copper grade of 16% and recovery of 70%，the sulfur grade of pyrrhotite concentrateafter magnetic

separation is 30%，the recovery rate is 36%，and the sulfur grade of sulfur concentrate is 40%，the recovery

rate is 45% can be obtained.Good separation effect of copper and sulfur is obtained.
