Title

(EN) Copper ion flotation with cationic reagents

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.
