摘要
以铜冶炼过程中杂质元素砷、锑、铋为对象,通过对比分析实际生产数据,初步理清了砷、锑、铋在铜冶炼过程中不同工艺及工序中的分布情况.结果表明,不同冶炼工艺中砷、锑、铋的分布情况有较大差异,赋存在铜精矿中的砷、锑、铋经过熔炼、吹练、电解精炼过程后,主要流向烟尘、炉渣、阳极泥及黑铜等副产品中.介绍了近年来从铜冶炼副产物中回收砷、锑、铋的主要方法、工艺流程、工艺参数以及取得的成果.
In this paper,the impurity elements such as arsenic,antimony and bismuth in the copper smelting process were used as research objects.By comparing and analyzing the actual production data,a preliminary understanding has been made of the distribution of arsenic,antimony and bismuth in different processes in the copper smelting.The results show that the distribution of arsenic,antimony and bismuth in different smelting processes is quite different.Arsenic,antimony and bismuth in copper concentrates are mainly converted to by-products such as dust,slag,anode slime and black copper after smelting,blowing and electrolytic refining.The main methods,technological process,technological parameters and achievements in recent years are introduced of recovering arsenic,antimony and bismuth from by-products of copper smelting.
