Abstract

L'invention porte sur un procédé pour la lixiviation d'or à partir d'un minerai d'or contenant de la pyrite, le taux de lixiviation de l'or étant amélioré sans nécessiter l'utilisation d'une substance chimique hautement toxique telle qu'un cyanure, la thiourée, l'acide thiosulfurique et un halogène gazeux. Le procédé pour la lixiviation d'or comprend : une étape de prétraitement comprenant une étape (1) consistant à utiliser un minerai d'or contenant de la pyrite et une étape (2) consistant à oxyder et griller le minerai d'or; et une étape (3) consistant à mettre le minerai d'or prétraité en contact avec une solution de lixiviation de l'or contenant un ion halogénure tout en introduisant un agent oxydant pour ainsi lixivier un constituant de l'or à partir du minerai, et ensuite effectuer une séparation solide/liquide du produit ainsi obtenu en une solution contenant de l'or lixivié et un résidu contenant du fer.
