摘要
传统选冶提铜工艺因成本高、经济效益差和资源利用率低等缺点制约其难于处理低品位硫化铜矿,生物浸出技术是处理低品位硫化铜矿的有效方法,对提高我国铜资源开发利用率、缓解我国优质铜矿供需矛盾突出和提升铜矿资源的服务保障年限具有重要的意义。本文采用生物提铜萃余液对某低品位次生硫化铜矿柱浸180d,尾渣铜品位由0.23%降低至0.064%,铜浸出率为72.17%。
The traditional smelting process of copper is difficult to deal with the low-grade sulfide copper ore because of the shortcomings of high cost,poor economic benefit and low resource utilization.Biological leaching technology is an effective method for processing low grade sulfide copper ore,which can improve China's copper resources development and utilization,and resolve the highlight contradiction between supply and demand of high quality copper,also has important significance can improve service life of copper resource.In this paper,we use biological copper extraction to deal with a low-grade secondary copper sulfide ore,after column leaching180 days,the copper grade of tailings was reduced from 0.23%to 0.064%,and the copper leaching rate was 72.17%.
