ABSTRACT:

As an extension of the work on the effect of OH- on various cations in hydrometallurgical systems, the effect of Cl^-, Br^-, I^- and CN^- on cations such as Ag⁺, Cd²⁺, Hg²⁺, Cu⁺, Cu²⁺, Co²⁺, Zn²⁺, Pb²⁺ and Sn²⁺ has been examined in detail. The Newton-Raphson technique has been used to determine the amounts of various metal species as a function of the concentration of anions. Some practical implications of various metal complexes in metal separation and removal from solutions have been examined and discussed.
