Jan 01 2016 · Specific areas of expertise include the treatment of refractory gold ores using bacterial oxidation and management of metallurgical test programs and feasibility studies A new technique of advanced ozonation extraction AOE is under patent and currently being trialed for improving metal recovery from complex ores and wastesread more
Discovering new ground If you are looking to extract gold from refractory lowgrade ores we are introducing a gamechanger to the entire gold mining industry Your reserves containing refractory gold considered below the cutoff grade are not considered reserves because the cost of extracting it using pressure oxidation and bioleaching is tooread more
Apr 01 1995 · Abstract Gold in arsenopyrite or higharsenic pyrites commonly exists as submicroscopic or “invisible” inclusions making it refractory to cyanide leaching Current practice favour an oxidising roast to liberate the gold for cyanidation because it is fast and energeticallyread more
This process is very similar to the CIP process The main differences lie in the preparation of the slurry and method for removing the gold from the leachate In a CIL process the carbon is mixed with the leachate solution not with pulp This is a much less abrasive system meaning that the carbon lasts much longer than in a CIP processread more
Chromium processing preparation of the ore for use in various products Chromium Cr is a brilliant hard refractory metal that melts at 1857 °C 3375 °F and boils at 2672 °C 4842 °F In the pure state it is resistant to ordinary corrosion resulting in its application as an electroplatedread more
