Title
(EN) IRON CONTROL IN LEACHING
(FR) LIXIVIATION MAÎTRISÉE DU FER
Abstract
(EN)
A method for controlling iron precipitation from acidic ferric sulphate leach solutions in leaching of chalcopyrite and/or pyrite, the method comprising the steps of: increasing the rate of formation of a ferric basic sulphate and/or promoting precipitation of a ferric basic sulphate; and precipitating the ferric basic sulphate at a desired location
(FR)
L'invention concerne un procédé permettant de maîtriser la précipitation de fer dans des solutions de lixiviation de sulfate ferrique acide pour la lixiviation de chalcopyrite et/ou de pyrite. Le procédé consiste à augmenter la vitesse de formation d'un sulfate basique ferrique et/ou favoriser la précipitation d'un sulfate basique ferrique; et faire précipiter le sulfate basique ferrique à un emplacement désiré.
