随着工业的发展,世界上对金属的需求量不断增加,贫矿和深部矿的利用已经提到议事日程。但是,常规采矿、选矿和冶炼方法的能源消耗很高,导致高的生产费用,对上述矿石的处理往往是不经济的。另一方面,硫化矿和高硫燃料的环境污染也是人们十分关注的问题。为此,各国矿冶专家竞相寻找贫矿、深部矿石的利用途径。要求这些新技术:一要生产费用低,二不要造成环境污染。细菌浸出就是这些新技术中的一
With the development of industry, the demand for metal in the world is increasing, and the utilization of lean mines and deep mines has been put on the agenda. However, the high energy costs of conventional mining, beneficiation and smelting processes result in high production costs and the processing of such ores is often uneconomical. On the other hand, environmental pollution of sulfide ores and high-sulfur fuels is also a matter of great concern. To this end, national experts in mining and metallurgy competing to find lean, deep ore utilization. Requires these new technologies: one to low production costs, and two do not cause environmental pollution. Bacterial leaching is one of these new technologies
