2016-9-12 gold and obtain a concentrate for further cyanidation. Re-fractory ores, however, require fine grinding and a further pre-treatment step, such as roasting and pressure oxidation, 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.
