  • Cyanide Use in Gold Mining - Earthworks

    The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted. Vat (or tank) leaching: The ore is mixed with cyanide solution in large tanks.
