Leaching and recovery of gold from ore in cyanide-free

01/11/2020· The reason for lower holistic gold recovery in CIL method compared to carbon-in-PLS could be attributed to a slower gold extraction from the ore to the solution, which in turn reduces holistic recovery. This assumption was supported by observing 72% extraction of gold from ore into the solution in the CIL-1 test, while longer retention time (36 h) enhanced the dissolution of gold to 83% (CIL-2).
