    Oct 20, 2014 ABSTRACT. As easily mined gold deposits are becoming increasingly rare, gold producers are turning to the processing of ores with polymetallic and copper mineralization. These base metals can create metallurgical and waste handling/disposal challenges, which can render the project uneconomic.

  • Characterization of refractory behaviour of complex gold/silver ore

    A suitable pretreatment process is often required to overcome the refractoriness and render the gold accessible to the lixiviant action of cyanide and oxygen. [4]. Roasting, pressure oxidation, biooxidation, ultrafine grinding and modified cyanidation are the pretreatment methods currently practiced for refractory gold ores and.

  • Advances in the Cyanidation of Gold Gold Ore Processing (Second

    May 13, 2016 Abstract. Cyanidation, a process used for over a century to extract gold from free milling ores, is so effective that it can economically treat lowgrade ores (0.5 g/t Au). The concentration of cyanide added to dissolve gold is much higher than the stoichiometric requirement because of various interferences.
