介绍了铜阳极泥冶炼废水来源以及环境危害,通过对比分析3种不同的废水处理方式,选择使用硫化法处理铜阳极泥冶炼废水,并对中间产物进行成分检测与回炉处理.研究发现,硫化法能有效去除废水中的砷等有害元素,同时捕收金、银等贵金属.中间产物经分批回炉处理,不仅能减少环境污染,还能显著提高贵金属回收率,且回炉处理后,主产品阳极板中的杂质成分波动较小,表明对后续工序无显著影响.经济效益分析表明,回收中间物料中的金、银、铜等金属元素,能有效降低企业运营成本,增加经济效益.
Industrial Practice on Recovery of Precious Metals from Copper Anode Slime Smelting Waste water
This paper introduces the source of copper anode slime smelting wastewater and its harm to the environment.By comparing and analyzing three different wastewater treatment processes,the vulcanization process is selected to treat the copper anode slime smelting wastewater,and the intermediate products are subjected to the composition detection and recycling treatment.It is found that the vulcanization process can effectively remove harmful elements such as arsenic in wastewater and recover the precious metals such as gold and silver at the same time.The intermediate products are recycled in the furnace in batches,which not only reduces environmental pollution,but also significantly improves the recovery of precious metals.After the recycling treatment in the furnace,the fluctuation of impurity components in the main product is relatively small,indicating no significant impact on the subsequent operations.The analysis of economic benefits shows that the recovery of gold,silver,copper and other metal elements in the intermediate materials can effectively reduce the operating costs of enterprises and increase economic benefits.
