Gold cyanidation using hydrogen peroxide ScienceDirect

Gold cyanidation, using hydrogen peroxide, was considered by Knorre et al. and Habashi to be a slow process in which hydrogen peroxide inhibits the reaction by oxidizing cyanide to cyanate. On the other hand, Day [6] found no direct relation between the behavior of the gold dissolution rate and cyanide or peroxide concentrations.

Gold cyanidation, using hydrogen peroxide as an oxidising agent, has been studied by performing kinetic experiments, open circuit potential measurements and voltammetry. Small amounts of hydrogen peroxide make the cyanidation rate lower than that in conventional cyanidation, but higher amounts can make the cyanidation rate double.
