extraction process to remove gold from oreGold Processing Methods Gold Ore Extraction. Of all the methods of extracting gold processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration.
Processing technologies for goldtelluride oresto render the gold ores amenable to extraction. Usually, gold telluride ores appear to be refractory as they are always associate with pyrite and other sulfides. This would 'lock' the gold and give rise to elevated cyanide consumption. For this reason, oxidative pretreatments are generally conducted to improve gold recoveries. Table 1.
