Thermodynamics of the aqueous copper–cyanide system ...

In conventional gold processing, the copper and complexed cyanide are not recovered after the gold is removed from the solution. This leads to a significant economic penalty in excess cyanide consumption, loss of a valuable copper by-product and significant cost in cyanide destruction during effluent treatment.
