很多过去曾经被认为是没有开采价值的金银矿床,随着黄金价格的上涨以及浸出和置换贵金属工艺的重大改进,现在已经变成为有开采价值的矿床了。各种活性碳吸附和解吸贵金属氰化物的方法都显示出了各自的优越性,从而在世界各国陆续建立了一些碳浆法选金厂,在采用堆浸和槽浸方法的选矿厂中,越来越广泛地在排水系统和尾矿回水系统中增设了碳柱 Much of the gold and silver deposits that used to be considered unexplored gold have now become mineable deposits as gold prices rise and significant improvements in leaching and replacement of noble metals are made. A variety of activated carbon adsorption and desorption of precious metal cyanide methods have shown their superiority, which in succession in the world have set up some carbon slurry gold refineries, heap leaching and tank dip in the use of beneficiation plant, the more More extensively, carbon columns have been added to drainage systems and tailings return systems
