Abstract

2112057PC 17 (57) ABSTRACT The invention relates to a method for enhancing reactor volume use in a leaching stagein a hydrometallurgical process. According to the method, a concentrate or cal- cine leaching stageis carried out primarily using a plurality of reactors arranged in series, one or more reactors being provided with liquid-solid matter separation and the sepa- rated solid matter being transferred to one of the reactors in the leaching stage.

L'invention concerne un procédé d'amélioration de l'utilisation d'un volume de réacteur dans un stade de lixiviation dans un procédé hydrométallurgique. Selon le procédé, une étape de lixiviation de concentré ou de produit calciné est effectué principalement à l'aide d'une pluralité de réacteurs disposés en série, un ou plusieurs réacteurs étant pourvus d'une séparation de matière liquide-solide et la matière solide séparée étant transférée dans l'un des réacteurs dans le stade de lixiviation.
