摘要
开发出一种成本低、环保、高效处理铅阳极泥的新型复合冶炼工艺,该工艺能将金银富集4倍;有害金属As以砷酸钠产品形式开路除去,开路率大于70%;铅、锑以合金形式回收进生产流程,回收率大于80%。
A new composite metallurgical process with the characteristics of low cost,environmental friendly and high efficiency were developed to treat lead anode slimes.With the process,the gold and silver would be enriched by 4 times,the harmful metals As was removed with open circuit as sodium arsenate,and the open circuit rate was over 70%,lead and antimony recycled into the production process in the form of alloy,and the recovery rate was over 80%.
