Copper and Cyanide Recovery in Cyanidation Effluents

recovery of gold from Merrill-Crowe process cyanide solution, involves two different operations: 1) gold dis-solution, where it is oxidized and dissolved to form Au (I) ion and cyanide complex 2, and 2) precipitation by reduction of metallic gold. In the cyanidation process, free cyanide ions in solution can only be provided at a pH of 9.0.
