Gold Processing Methods Gold Ore Extraction

This was a geometallurgy exercise in which 8 lithologies from the same open-pit gold deposit were tested for Silver and Gold Extraction and evaluation of the response for 2 Processing Methods. The feed gold and silver was amenable to gravity separation and flotation. However, the subsequent cyanidation of the concentrates did not provide any significant improvement, on average, over Whole-of-Ore CIL testing.
