摘要
针对铜冶炼渣性质特点,对渣中铜、铅、锌、铁的赋存状态进行分析,制定了优化试验方案,在小型试验研究的基础上,开展了工业试验研究,实现炉渣原矿品位:Cu 1.699%、Au 0.358 g/t、Ag 29.786 g/t;铜精矿含Cu品位18.662%,含Au 2.81g/t,含Ag 64.705 g/t;铜精矿中Cu实际回收率79.494%,Au实际回收率59.612%,Ag实际回收率71.597%;尾矿中含Cu 0.366%。
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%,respectively.The copper content in the tailings was 0.366%.
