ION FLOTATION PROCESS, GOLD EXTRACTION PROCESS USING ION FLOTATION, COMPOUND, AND, CATIONIC TENSIVE ACTIVE

摘要

A method for ion flotation, especially in the extraction of gold 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.
