  • Processing Gold Ores Using Heap LeachCarbon

    Processing Gold Ores Using Heap Leachcarbon

    The chemistry involved in the dissolution of gold in the heap-leach cya- nidation treatment is the same as that for the agitation-cyanidation process. In heap leaching, the oxygen, essential for the dissolution of gold, is intro- duced into the cyanide solution as it is being sprinkled upon the ore heap.

    In the recovery of gold, a cyanide solution is evenly distributed across the top of the heap. The issue is the flow of the solution quickly slows due to the ores natural composition. This creates an extended leaching process, adding to operating costs and reducing the amount of gold recovered. Ethox 4804 is the answer to these costly problems.
