Elution and Carbon Reactivation

conditions elution (desorption) of gold from the carbon occurs The main factor that makes desorption or stripping a simple process is the fact that gold will only adsorb onto carbon at low temperatures If the temperature of a solution and carbon mixture is increased the gold will readily desorb from the carbon into the solution TemperatureGet price

Gold cyanidation

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex It is the most commonly used leaching process for gold extraction Production of reagents for mineral processing to recover gold copper zinc and silver represents Get price


Processing smelting and refining gold

The two gold refining methods most commonly employed to derive pure gold are the Miller process and the Wohlwill process The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold Get price


Refining Gold

The final stage of gold production -- refining-- involves removing impurities that remain after the smelting process Refining companies receive dor bars as well as scrap gold and reliquefy the metal in a furnace Workers add borax and soda ash to the molten metal which separates the pure gold from other precious and less precious metals Get price


Silver processing

A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve This is called inquartation and the separating of silver and gold by leaching with nitric acid is referred to as parting Get price


Cyanide Leaching Of Gold

Once the gold has been dissolved in the cyanide and the ore body has been reasonably depleted of its gold there are two main processes for recovering the gold from the pregnant cyanide solution One is the Merrill-Crowe zinc precipitation process and the other is the adsorption of the gold Get price
