Abstract

L'invention concerne un procédé de prétraitement de minerai d'or de façon à lixivier l'or à partir de minerai d'or contenant de la pyrite, avec lequel il est possible de supprimer la production de dioxyde de soufre et d'améliorer le taux de lixiviation de l'or. L'invention concerne un procédé de prétraitement de façon à récupérer de l'or contenu dans un minerai d'or contenant la pyrite (FeS2) par traitement en voie humide, le procédé contenant une étape dans laquelle la pyrite dans le minerai d'or est convertie en un composé de fer soluble dans l'acide chlorhydrique.
