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.
Gold Leaching. Gold leaching is the chemical mineral processing method used for gold Extraction. Cyanidation and gold leaching achieve new levels of safety and performance in even the most difficult applications far surpassing the performance of other forms of gold leaching equipment.
