Abstract

Cette technique de lixiviation biologique permettant de procéder à la lixiviation de minerai ou de concentrat renfermant un sulfure, consiste à soumettre à une lixiviation biologique une bouillie renfermant de l'oxygène et du dioxyde de carbone dissous, un sulfure et des micro-organismes, ainsi qu'à agir sur le potentiel d'oxydo-réduction de la bouillie pour maintenir cette oxydo-réduction dans une plage prédéterminée.
