Electrolytic tank gold ore processing cost new

A new and effective electrochemical process for the extraction of gold, silver and other precious metals from low-yield ores containing relatively large quantities of other non-precious metals wherein a novel electrolytic dissolution cell is provided for the controlled production and efficient utilization of chlorine as a solubilizing agent for the removal of the precious metals from the ore

    Gold Refining | From Gold Ore to Doré | World Gold Council

    From ore to dor . More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore
