| Abstract: | The characteristics and occurrence state of associated gold and silver in a Yunnan copper mine were detailed studied in this paper. On the basis of this research results, the technical transformation of existing technology was carried out. Middlings regrinding, then classification, lastly the classifier overflow was returned to roughing. when the grinding fineness of middlings up to 63% of -0.048mm, The recovery of gold and silver in copper concentrate increase by 15.2% and 15.8% respectively. |
