gold ore sulfide

  • As the gold is encapsulated in sulfide minerals such as pyrite and arsenopyrite, the gold is prevented from being leached by cyanide. The BIOX process destroys sulfide minerals and exposes the gold for subsequent cyanidation, thereby increasing the achievable gold recovery. Improves rates of gold recovery ; Reduces capital costImproved recovery of a low-grade refractory gold ore using ...In sulfidic refractory gold ores, fine gold particles may be highly disseminated and locked up in sulfide minerals such as pyrite and arsenopyrite. All the largely unoxidized ores exhibit very low gold recoveries (typically <20%) by direct cyanidation.differences in processing sulfide and oxide gold ores ...gold ore roasters for sale – Grinding Mill China.
