  • Heap Leaching of Gold and Silver Ores - ScienceDirect

    Jan 01 2016 Stacking the ore with trucks can result in the tie-up of a large tonnage of ore below the truck roadways. This is a bigger problem on small operations than on large ones because the roadway width is nearly the same regardless of the daily production rate. For a heap leach of 5000 td the roadways on the heap can tie up 1 month's ore production.

    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.
