To render the gold ores amenable to extraction. Usually, gold telluride ores appear to be refractory as they are always as-sociate with pyrite and other sulfides. This would ‘lock’ the gold and give rise to elevated cyanide consumption. For this reason, oxidative pre-treatments are generally conducted to improve gold recoveries. Table 1.
