This can be followed by counter-current decantation with the resulting pregnant leach solutions (PLS) fed to the existing SX-EW facility. The higher copper tenor PLS can either be blended with the lower copper tenor PLS from the existing heap leach facility, or it can be fed directly into the existing SX-EW plant. Potential applications

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.

Bioleaching can occur directly via microbial contact with ores or indirectly by microbes producing leaching agents. Common applications include copper, uranium, gold and silver, and silica leaching. Bioleaching is used commercially in slope, heap, and in situ leaching with ores placed in piles or left in the ground and irrigated with microbes.
