    Thiosulphate Leaching Thiosulfate leaching is a process that recovers gold from ore without the use of cyanide. SGS developed the thiosulfate leaching process because in some jurisdictions, increased regulation pressure means that cyanide cannot be used or transported. We are a global technical leader in the field of thiosulfate leaching.

  • Cyanide Use in Gold MiningEarthworks

    Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metalimpregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted.
