针对某含金铜废石进行了详细的试验研究，结合矿石性质，即部分金铜矿物嵌布较粗，本次采用金铜部分快速优先浮选工艺，实现了含金铜废石资源化利用。废石中含金0.41×10-6、铜0.17%，经部分快速优先-一粗-三精-三扫闭路流程，获得含金26.26×10-6、铜13.34%的金铜精矿，金回收率达63.16%，铜回收率达79.23%，选矿效果较好，值得在同类型矿山进行推广应用，可有效提高矿山资源综合利用水平。
針對某含金銅廢石進行瞭詳細的試驗研究，結閤礦石性質，即部分金銅礦物嵌佈較粗，本次採用金銅部分快速優先浮選工藝，實現瞭含金銅廢石資源化利用。廢石中含金0.41×10-6、銅0.17%，經部分快速優先-一粗-三精-三掃閉路流程，穫得含金26.26×10-6、銅13.34%的金銅精礦，金迴收率達63.16%，銅迴收率達79.23%，選礦效果較好，值得在同類型礦山進行推廣應用，可有效提高礦山資源綜閤利用水平。

An experimental research on certain gold copper waste rock has been completed,combined the analysis of ore properties,namely,some of the gold inlaid copper mineral were coarser.Therefore,the rapid selective flotation process of gold copper waste rock was applied in this study,which made the resource utilization of gold copper waste rock come true.The waste stone grade was gold 0.41×10-6,and copper 0.17%,respectively.However, after some rapid priority and the three closed circuit process,the gold copper concentrate with gold 26.26×10-6, and copper 13.34% can be attained,indicating that gold recovery rate was 63.16%,the copper was 79.23%,and the separation effect was good.Thus,the method was worth of popularization and application in similar mines,and can effectively improve the level of comprehensive utilization of mine resources.
