Abstract
La présente invention concerne un procédé amélioré pour la récupération de métal à partir de minerai à l'aide d'une lixiviation par agitation, comprenant la division de la lixiviation du minerai broyé et exploité en au moins deux circuits secondaires d'extraction avec solvant pour une séparation solides/liquides de lixiviation, sans dilution significative lors de la séparation solides/liquides dans ces unités, et le raffinat provenant de l'extraction avec solvant étant recyclé vers la lixiviation. La pulpe de tamisat provenant du second séparateur solides/liquides est envoyée vers un séparateur solides/liquides final, avec lavage à l'eau, à partir duquel les solides lavés sont envoyés vers l'évacuation et la solution de lavage aqueuse clarifiée est envoyée vers une extraction avec solvant finale, une partie ou la totalité du raffinat aqueux appauvri en métal provenant de cette extraction avec solvant finale étant facultativement neutralisée et/ou étant mise à circuler pour repartir vers la troisième séparation solides/liquides sous forme de solution de lavage et/ou vers la récupération d'autres métaux et/ou vers l'évacuation afin de maximiser la récupération de métal et de conserver l'équilibre en eau.
