智利某含金银铜尾矿选冶实验研究

Experimental Study on the Dressing and Smelting of A Tailings Containing Gold,Silver and Copper in Chile

以智利某含金银铜浮选尾矿为研究对象,在对试样进行化学多项分析、铜物相分析以及金的化学物相分析等研究基础上,采用硫酸优先浸铜再氢化浸金银工艺,铜浸出率为83.03%,金浸出率65.22%,银浸出率76.35%,可为同类型矿石的综合利用提供技术参考。

Taking a flotation tailings containing gold,silver and copper in Chile as the research object and on the research basis of chemical multianalysis,copper phase analysis and chemical phase analysis of gold,the technology of leaching copper with sulfuric acid and then leaching gold and silver with it after being cyanide was adopted.The copper leaching rate was 83.03%,gold leaching rate was 65.22%,and silver leaching rate was 76.35%,which can provide a reference for the comprehensive utilization of the same type of ore.
