Gold and silver can be recovered by gravity for the free gold/silver followed by cyanidation of the lower grade ore to make doré bars on site from both products. Alternatively, after gravity, a flotation step can be used to produce a lower grade concentrate to be shipped to smelters worldwide for final processing.
