The invention relates to a method for the stabilization of the production capacity of an extraction plant extracting metals in a process, where the metal content of the feed solution varies. For the stabilization of capacity, the extraction cells and their piping are constructed and situated in such a way, that the extraction stages can be connected in different combinations, either in parallel or in a series. The method is especially suitable for the copper extraction process.
L'invention porte sur un procédé de stabilisation de la capacité de production d'une installation d'extraction des métaux dans un processus où la teneur en métal de la solution d'amenée varie. Pour stabiliser la capacité, on construit et on place des cellules d'extraction et leurs conduites de façon que les étages d'extraction puissent être raccordés selon différentes combinaisons, soit en parallèle, soit en série. Ce procédé est notamment approprié pour le processus d'extraction du cuivre.
