提金尾渣的再利用

Recycling the residues from gold extraction

对于黄金矿山来说,氰化尾渣中尚有可回收的金、银、铜、铅等有价金属元素.综合回收这些金属,既可以为矿山创造经济效益,同时减少了尾矿对环境的污染.

There are a number of valuable metals such as gold, copper, leader and silver remaining in the residues from gold extraction. Recycling these metals can not only gain economic benefits, but also decrease the pollution to environment by the residues.
