Title (EN) LEACHING AIDS AND METHODS OF USING LEACHING AIDS
(FR) ADJUVANTS DE LIXIVIATION ET LEURS PROCÉDÉS D'UTILISATION
Abstract:
(EN) Leaching aids, for example, when present in a leaching solution, and methods of using the leaching aids. The leaching aids can include one or a combination of compounds. The method of using the leaching aids can include a process of recovering metal from ore, for example, a process involving heap leaching, solvent extraction and electrowinning.
(FR) La présente invention concerne des adjuvants de lixiviation, présents par exemple dans une solution de lixiviation, ainsi que leurs procédés d'utilisation. Les adjuvants de lixiviation peuvent contenir un composé ou une combinaison de composés. Le procédé d'utilisation des adjuvants de lixiviation peut comprendre un processus de récupération de métal à partir de minerai, par exemple un processus supposant une lixiviation en tas, une extraction par solvant et une extraction électrolytique.
