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

2017-5-1  Copper extraction from gold-copper oxides by GCS and conventional cyanidation processes at leach conditions of 50% solid contents, 100%-75 μm, pH 11.0 and room temperature. In GCS process, most of the dissolved copper were complexed by glycine which leads to be more available cyanide to leach and complex gold.
