The above pre-treatment stages can be changed based on ore mineralogy. For a complex Au–Ag ore, direct cyanide leaching resulted in only about 47% and 19% extraction of gold and silver even after very fine grinding at <38 µm.Diagnostic leaching was carried out to assess the nature of refractoriness [29].Depending on the results of the diagnostic test …
