根据戈勒姆国际公司(Gorham International Co)所承接的研究项目和正在解决的微生物研究课题推测,用微生物从精矿中萃取和浓缩战略金属和贵金属的产值,到2000年时,可达50亿美元。目前仅就美国,使用微生物水冶所生产的铜产值为3500万美元,铀为200万美元。微生物水冶具有优越于通常的水冶法若干特有的优点,例如可以处理品位相当低的矿石,金属含量非常微的污水,投资和生产费用都比较低。
According to the research project undertaken by Gorham International Co and the ongoing research project on microbiology, the value of extracting and concentrating strategic metals and precious metals from concentrates using microorganisms is estimated to reach 5 billion by 2000 Dollars. At present, only the United States, the use of microbial watermelon produced copper output value of 35 million US dollars, uranium was 2 million US dollars. Microbial hydrometallurgy has several unique advantages over the usual hydrometallurgical methods, such as the ability to treat relatively low-grade ores, sewage with very low metal content, and low investment and production costs.
