    Copper complexes that can be present in cyanide liquors include Cu (CN) 2 −, Cu (CN) 3 2 −, and Cu (CN) 4 3 − with the proportions dependent on the pH, copper concentration, and free cyanide concentration. The main issue facing the process engineer is the fact that minimization of cyanide consumption is favored by the formation of species with a low copper cyanide mole ratio, e.g., Cu.
