随着我国有色冶金工业的迅速发展,在采矿、选矿、冶炼过程中,出现了大量低品位的含铜废石、尾砂和贫矿等,这些物料过去由于没有找到经济而有效的处理方法,一直未得利用。近十多年来,美国、日本、澳大利亚等国家,先后对采用细菌冶金处理此类低品位物料进行了大量的工业性试验研究工作,有的已经正式投入生产。为了进一步扩大我国铜矿资源的利用程度,本文着重介绍一下国外从细菌冶金浸出液中回收铜的概况,供同志们参考。
With the rapid development of non-ferrous metallurgy industry in our country, a great deal of low-grade copper-bearing waste rock, tailings sand and lean ore appear in the process of mining, mineral processing and smelting. In the past, these materials were not found to be economical and effective treatment methods, Has not been used. In the past decade or so, the United States, Japan, Australia and other countries conducted a large number of industrial experiments and studies on the treatment of such low-grade materials using bacterial metallurgy. Some of them have been officially put into production. In order to further expand the utilization of copper resources in our country, this article focuses on the overview of recovery of copper from bacterial metallurgy leaching solution for your reference.
