In the case of the higher energy consumer, the pregnant liquor is pumped five miles from the leach site to the SX/EW plant. The electrowinning of copper requires considerably more electrical energy than does the electrorefining process - an average of about 8 MJ/kg for electrowinning vs about 1.5 MJ/kg for electrorefining.
On the other hand, the addition of ammonia into the Gedabek leaching plant was not found to improve gold recovery (i.e., gold recovery remained constant at 72.5%). Another study by Bas et al. on leaching copper-rich gold ore (56 ppm Au and 1.1% Cu) using mixtures of ammonia and cyanide indicated both improvements in gold recovery and cyanide ...
