  • Precious Metal Heap Leach Design and Practice

    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.
