Gold and copper leaching from gold-copper ores and ...

2017-5-1 · Gold and copper extraction from gold-copper sulfides ore, containing 0.77 ppm Au and 0.15% porphyry Cu (mainly present as chalcopyrite), has been calculated and presented in Fig. 3, Fig. 4 respectively. Fig. 3 shows that by adding 2 g/L glycine at similar cyanide concentration (450 ppm NaCN), gold extraction increased from 29.2% to 38.9%.

Gold-Copper Ores - ScienceDirect

2016-1-1 · 1. Introduction. The association of gold and copper mineralization in commercially viable ore is a common occurrence. At one end of the spectrum is the predominantly copper ore, which contains levels of gold mineralization. This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value.
