摘要
当前,环境法规变得越来越严格,环境保护成本继续上升。很有必要更有效地利用二次资源,从中回收金属,减少资本支出和解决环境影响问题。利用微生物法回收金属工艺,被认为是最具应用前景的方法之一。这是由于生物湿法冶金在温和的条件下进行,通常不使用任何有毒化学品。因此,加大生物湿法冶金从尾矿和贫矿中回收金属的应用,使其成为一种提高金属产量的环保型生物技术意义重大。
As environmental regulations become ever more stringent,the costs for ensuring environmental protectionwill continue to rise.There is a need to make more efficient use of technologies to recover metals from secondaryresources,reduce capital expenditure and address environmental impacts.Metal recovery by microorganism isconsidered to be one of the most promising methods.This is due to the fact that bio-hydrometallurgy is carried outunder mild conditions and usually does not use any toxic chemicals.Therefore,it is of great significance to increasethe application of bio-hydrometallurgy to recover metals from tailings and lean ore and make it a kind ofenvironmental protection bio-technology to improve metal yield.
