Processing Gold from Sulfide Ores Assaying, Microscopy,
They said it had a lot of silver and copper, but no gold. 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.
