The Use of Equilibrium Diagrams to Better Understand the Influence of Lead Additions on Gold Leaching in Aqueous Cyanide

The leaching of gold in alkaline aqueous cyanide solutions may be reduced significantly by the passivation of the gold by a surface layer of polymeric aurocyanide. This passivation of the gold is typically countered by the presence of Pb(+2) species in solution, which may be present as an impurity in the solution, or specifically added for this purpose. The speciation and availability of Pb(+2) in typical cyanide leach solutions is illustrated as a function of pH, and the presence of S(-2), S(+6), Cu(+1) and Ag(+1) species. The probable role of the Pb(+2) species in efficient gold leaching is discussed.
