    A copper mine in Safford, AZ uses an ore extraction process called heap leaching. Engineers needed to limit the application rate of the extraction solution to maintain slope stabilities. This resulted in a reduced recovery rate of the leachate solution.

  • The bioleaching of sulphide minerals with emphasis on

    The most successful copper heap leaching operations have been those processing copper oxides and secondary copper sulphides ().Chalcocite (Cu 2 S) is the main copper sulphide mineral mined at bioleaching operations. Some of the chalcocite heap operations began as oxide (chemical) leach operations and were converted to bioleach (oxidative) operations by heap aeration and/or inoculation,

  • Heap Leaching Using Uncertainty and Global Sensitivity

    Heap leaching allows the processing of low grade metallic minerals (for example, less than 1% copper) [1,2]; nonmetallic minerals [3,4], and potentially yttrium and heavy rare earth elements [5]. In fact, heap leaching is often the preferred method for extracting metal from low grade ore deposits as it provides a low capital cost compared to

If the ore grade is high (.7 to 1.2% T, Cu) the early solution off the pad will be 30 g/l copper or higher. In 6 meter and 15 meter column tests early OFF solutions have been as high as 70 g/l copper. c.

    Oxygen is an essential element in the leaching process. Efficient heap leach operations require that oxygen plus the acid or biological agent be present to dissolve the mineral deposits into the leach solution. In general, the higher the oxygen level, the greater the mineral recovery. Applying too much leach solution saturates the crushed ore and drives out the oxygen.
