2016-1-1 Gold extraction increased and copper solution levels were reduced markedly. Copper levels as high as 1500 mg/L in the fifth leach tank were common prior to oxygen injection and as the trial progressed, copper levels dropped uniformly. In addition, cyanide and ammonia levels were reduced without adversely affecting gold extraction, which in turn led to a further decrease in solution copper

2006-8-1 The same extraction experiments as above were performed with the experimental results in Fig. 7(b) showing that copper has a small effect on the extraction of gold by N 1923 /n-octane. The extraction of gold decreased from 66.1% to 62.7%, whilst the extraction of copper increased from 21.8% to 23.6% at pH 7.5. There was little effect on the extraction of gold by N 1923-TBP/n-octane, the extraction of copper
