In order to eliminate the huge capital costs associated with the purchase and installation of solids/liquids separation equipment, techniques have been developed that circumvent the entire separation process. One of these is the addition of granular activated carbon to the ore slurry during or uponpletion of gold solubilization. The dissolved gold is readily adsorbed onto the carbon, thus removing it from solution, and the granular carbon is separated from the now barren ore by running the slurry through a screen. Gold is then leached from the carbon particles by a strong solution of sodium cyanide and sodium hydroxide, and it is recovered from solution by electrowinning directly onto steel wool or by the Merrill-Crowe process. In the latter process, the gold-bearing solution is deoxygenated and passed through a filter-press, where the gold is displaced from solution by reduction with zinc metal powder. @GroundTruthTrek:The future needs less energy than we thought. Over the past 5 years, increasing efficiency has shrunk official... t.co/l4LqKqxV The ore ...
