Abstract

L'invention concerne un procédé pour le prétraitement d'alimentation vers un bioréacteur de lixiviation en tas de surface non agité par l'application en séquence de première et seconde solutions de prétraitement à une alimentation vers un bioréacteur de lixiviation en tas de surface non agité, la première solution ayant une teneur en fer supérieure à 5 g/l et un pH inférieur à 2, et la seconde solution contenant une population microbienne sensiblement supérieure. L'invention concerne en outre des procédés pour adapter une population microbienne à une utilisation dans un bioréacteur de lixiviation en tas de surface non agité.
