Treatment of copper-rich gold ore by cyanide leaching ...

2015-3-2 · Figure 6 illustrates that the pretreatment by ammonia leaching renders the ore amenable to high extraction of gold even at low levels of cyanide (1.5 g/L NaCN). In effect, the extraction of gold from the ore substantially improves from 6.7% to 99.8% after the ammonia pretreatment. This improvement appears to be linked with the elimination of copper interference by ammonia leaching. Over 24 h, 73% of copper is leached from the ore in this pretreatment stage. The remaining copper could be associated with chalcopyrite present in the ore. MUIR et al reported that copper dissolution from sulphides in ammonia is a slow process (Eqs. (7)−(9)) with relatively low copper
