Gold Extraction in Carbonaceous Ore using ThiosulfateExtraction of Gold

It is immediately apparent that under the proper conditions thiosulfate is a much better lixiviant for extracting gold from this carbonaceous ore than cyanide Without complete optimization of the leaching variables thiosulfate extracted about 65 pct of the gold compared to zero for cyanide It is also apparent that the thiosulfate consumption generally increased with gold extractionWith pyritic ores a preliminary roasting to eliminate sulphur is necessary The ore is reduced to a fine state of division and amalgamated simultaneously in a stamp mill the solid gold amalgam separated from the liquid mercury by filtration through leather under pressure and the mercury distilled
