  • Refractory Gold Ore Treatment Methods

    Where gold is associated with arsenic antimony tellurium and certain other minerals it is often only partly soluble in cyanide solution. The difficulty is usually more of a physical than a chemical one but special methods of treatment may be required.

  • Treatment of Refractory Gold Ores XPS

    Treatment of Refractory Gold Ores Extractive Metallurgy Once the cause has been identified there are a number of alternatives for treating the ore. Firstly the gold can be made more amenable to cyanidation by ultrafine milling followed by a hot atmospheric leach the Albion Process. A second solution is complete pressure oxidation (POX) which is effective for all conditions except

  • Processing Refractory Gold Hydrometallurgy: Leaching in

    Refractory ores are normally have either a high sulfide content that masks the gold preventing cyanide leaching of the gold or high organic content that also block gold leaching (reabsorbs the gold) or it can have a high clay content that also soaks up the cyanide. Other issues can be locked particles that are not exposed for leaching or coarse particles that take a long time to fully leach.

    Physical encapsulation. Also grinding the ore to an extremely fine particle size can liberate gold encapulsated in sulfides. SGS has very extensive experience with all the unit operations involved in the processing of refractory gold ores and in selecting the optimum flowsheet for a particular ore. Our gold metallurgy expertise is second to none.
