Behavior of anions in association with metal ions under hydrometallurgical environments: Part I — OH− effect on various cations
R Kim, HC Cho, KN Han - Mining, Metallurgy & Exploration, 2014 - Springer
A comprehensive analysis of the effect of OH− on various cations in hydrometallurgical
systems has been investigated. Cations chosen for this analysis included groups 1A and 2A,
rare-earth elements and other common transition metal ions such as Cu 2+, Fe 2+, Fe 3+,
Mn 2+, Ni 2+, Co 2+, Ag+, Cd 2+, U 4+, UO 2 2+, Hg 2+, Al 3+ and Zn 2+. The Newton-
Raphson technique was used to calculate and plot various metal species over a wide range
of pH. This study has clearly shown that by adjusting the concentration of OH−, the …

Behavior of anions in association with metal ions under hydrometallurgical environments: Part II — Effects of Cl−, Br−, I− and CN−
R Kim, HC Cho, KN Han - Mining, Metallurgy & Exploration, 2014 - Springer
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+, Cd 2+, Hg 2+, Cu+, Cu
2+, Co 2+, Zn 2+, Pb 2+ and Sn 2+ 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.
