Gold extraction - QueensMineDesignWiki

The challenge of attaining economic extraction of gold from refractory ores is one of the main challenges in the mining industry today, as less refractory ores become more depleted. It is thus important to properly select an extraction method for refractory ores, based on mineralogy, precious metal grades, gold to sulphur ratios and hazardous impurities (Mark Aylemore, 2008).
