Title (EN) METHOD FOR PERFORMING A BIOLEACHING PROCESS OF CHALCOPYRITE
(FR) PROCÉDÉ DE CONDUITE D’UN PROCESSUS DE BIOLIXIVIATION DE CHALCOPYRITE
Abstract:
(EN) The present invention relates to a method for performing a bioleaching process of chalcopyrite comprising the steps of: providing a chalcopyrite containing material; providing microorganisms, the microorganisms oxidizing iron(ll) at a rate such that the redox potential does not rise above 550 mV relative to a Ag+/AgCI electrode; adding said microorganisms to the chalcopyrite containing material; allowing reaction at said redox potential to provide copper ions.
(FR) La présente invention concerne un procédé de conduite d’un procédé de biolixiviation de chalcopyrite comprenant les étapes de : fourniture d’un matériau contenant de la chalcopyrite ; fourniture de micro-organismes, les micro-organismes oxydant le fer (ll) à un taux tel que le potentiel redox n’augmente pas au-dessus de 550 mV par rapport à une électrode Ag+/AgCI ; l’ajout desdits micro-organismes au matériau contenant de la chalcopyrite ; conduite de la réaction audit potentiel redox pour fournir des ions de cuivre.
