Gold cyanidation using hydrogen peroxide - ScienceDirect

01/04/1999  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. At low temperatures, the process is controlled by a

Improvements in gold ore cyanidation by pre-oxidation

01/07/2017  Previous experience in other gold extraction plants indicated the possibility of the use of hydrogen peroxide (H 2 O 2) for the purpose of pre-oxidation. AngloGold Ashanti's Siguiri plant in Guinea introduced oxygen supplementation via H 2 O 2 injection in the cyanidation circuit, and that resulted in an improvement in overall plant gold recovery from ∼90% to ∼94% (Verster, 2016). In ...
