Gold and copper leaching from gold copper ores and

Gold extraction from gold copper oxides at 300 ppm NaCN and 5 g/L glycine was 45.0% after 24 h which is much higher than gold extraction from gold copper sulfides (30.1% after 24 h at 450 ppm NaCN and 5 g/L glycine). This can be happen particularly when the sulfide is chalcopyrite and the leaching takes place at room temperature.
