Abstract
La présente invention se rapporte à un procédé de lixiviation (70) qui comprend les étapes suivantes consistant à : i) passer un métal qui contient un matériau résiduaire (72) d'une opération de traitement de minerais (96) à une étape de lixiviation biologique (74) au cours de laquelle une partie du métal est extraite d'une solution de lixiviation mère (76) ; et (ii) passer la solution de lixiviation mère (76) de l'étape i) à une récupération de métaux en aval.
