Based on the characteristics of copper smelting slag properties,the occurrence states of copper,lead,zinc,and iron in the slag were analyzed,and an optimized experimental plan was specified. On the basis of small-scale experimental research,industrial experimental research was conducted to achieve a slag raw ore grade of 1.699% Cu、Au was 0.358 g/t、Ag was 29.786 g/t;Copper concentrate has a Cu grade of 18.662%,Au content of 2.81 g/t,and Ag content of 64.705 g/t;The actual recovery rates of Cu,Au,and Ag in copper concentrate are 79.494%,59.612% and 71.597%,re-spectively. The copper content in the tailings was 0.366%.
