Introduction Of Heap Leaching Gold Selection_The Nile ...
Heap leaching is used to process 0.5-3g / t of low-grade ore, and the recovery rate of gold is 50-80%, and can even reach 90%. therefore, the heap leaching gold selection method can economically recover many small-scale gold mines, low-grade ore, tailings or waste rock that were originally considered to have no economic value.
