某锡铜共生矿降砷可选性试验研究

Experimental study on the reduction of arsenic in a tin copper symbiotic ore

某地锡铜共生矿矿体具有含量高,种类多,含砷高,部分砷矿物与铜矿物之间共生关系密切,具有"易浮难抑"的特点。导致铜生产指标不理想,铜精矿含砷高,铜砷分离成为一个大问题。为了提高铜精矿的质量,降低铜精矿中砷的含量,提高经济效益。

the tin copper symbiotic ore body in a certain place has high content,many species,high arsenic content,and a close relationship between some arsenic minerals and copper minerals,which has the characteristics of＂easy to float and difficult to restrain＂.The copper production index is not ideal,the copper concentrate contains high arsenic,and the separation of copper and arsenic becomes a big problem.In order to improve the quality of copper concentrate,reduce arsenic content in copper concentrate,and improve economic efficiency.
