Abstract

A hydrometallurgical process for the re-covery of precious metal values from refractory precious metal ore materials containing organic carbonaceous matter in which solubilized gold complexes are absorbed by leaching the ore with a thiosulfate lixiviant. A heap (1) of such particulate ore material is contacted with a lix-iviant solution (10) at conditions conductive to the formation of stable precious metal thiosul-fate complexes. Thiosulfate lixiviant is then recovered from the body of the ore particulates after a period of contact sufficient for the lix-iviant solution to become pregnant (20) with precious metal values, which values are then recovered from the lixiviant solution (80).
