Electrowinning process for extraction of gold

Jun 01, 2020

Apr 01, 1995 However, it has been shown that the extraction efficiency was not much affected by the gold concentration. This criterion was therefore used to analyze the effect of the elution conditions on the electrowinning process. The highest extraction efficiency was measured in Experiment 1 (83.5%)
