  • Intensive Cyanidation Leach Optimisation

    A big excess of Leach aid or leachwell in solution at the end of the leach can delay electrowinning Essentially it needs to be reduced at the cathode before gold will plate In the ILR we generally only use leachaid as an initial boost or if oxygen or peroxide is not available so we rarely encounter this I think the main issue for the Acacia is when the amount of gold or sulphides in the
