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).
Gold processing 101 - Mining Magazine
The hashing stage (corresponding to metal extraction and recovery stages) is a little more complex for gold ores, as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters, the gold mineralogical associations, and the gold particle size and liberation characteristics.
