    2019-9-11 · Ore from the Gedabek mine, which initially was mainly oxidic in nature, was treated by cyanide heap leaching to produce a pregnant leach liquor, from which gold was extracted by fixed-bed resin ion exchange. Resin ion exchange was used at Gedabek, instead of conventional activated carbon, because of the elevated copper concentrations in the leach liquors from the heaps, which typically Precious Metal Heap Leach Design and Practice,2020-6-24 · Comsur's Comco silver heap leach at Potosi, Bolivia, showed the same recovery in both a heap and an agitated leach plant. However, the silver ore leached very slowly and residence time of up to 4 days was needed in an agitated leach plant. Although the heap leach took several months to achieve the same recovery, the economics favored the heap.
