Processing Gold from Sulfide Ores - Assaying, Microscopy

A geologist said that the fire assay may not have extracted the gold from the ore, because of the various gold-silver-copper sulfur refractory compounds within due to a limited process that was used. This type of ore requires more extensive process steps to reduce the gold. We have tried various different methods of recovery, without success. Do you know what is the best method/process steps for recovering gold from this type of ore with sulfides

Sep 07, 2017 Sep 07, 2017 In the case of Goldstrike, this was a double-refractory ore combining sulphide-occluded gold with preg-robbing carbonaceous material that rendered the ore unsuitable for conventional cyanide leaching and carbon adsorption. In most cases, gold processing with cyanide leaching, usually with carbon adsorption, is still the core technology and the
