Title
(EN) COPPER ION FLOTATION WITH CATIONIC REAGENTS
(FR) FLOTTATION A IONS DE CUIVRE A L'AIDE DE REACTIFS CATIONIQUES
Abstract
(EN) A method for ion flotation of copper ions uses as the flotation reagent a cationic surfactant of formula (I), wherein R1 is a C10-C18 alkyl group, R3 is a lower alkyl group, or benzene ring optionally substituted with one or more lower alkyl groups, and R2 and R4 are lower alkyl groups; or R1, R2 and R4 are methyl groups; R3 is a benzene ring substituted with a C10-C18 alkoxy group; and X is a halogen atom.
(FR) Procédé de flottation à ions de cuivre utilisant à titre de réactif de flottation un tensio-actif cationique répondant à la formule (I), dans laquelle R1 représente un groupe alkyle C10-18; R3 représente un groupe alkyle inférieur ou un cycle benzénique éventuellement substitué par un ou plusieurs groupes alkyles inférieurs; et R2 et R4 représentent des groupes alkyles inférieurs; ou R1, R2 et R4 représentent des groupes méthyles; R3 représente un cycle benzénique substitué par un groupe alcoxy C10-18 et X représente un atome d'halogène.
