Resin-in-leach cyanidation of a carbonaceous gold ore ...

Resin-in-leach (RIL) cyanidation experiments were performed on a refractory carbonaceous gold ore. The objective of this investigation was to determine if strong-base ion exchange resins could adsorb the soluble aurocyanide complex in preference to natural “preg robbing” organic constituents. Direct cyanidation of the carbonaceous gold ore used in this study resulted in less than 2% gold ...
