On the physicochemical features of the interaction of the complexing collector IM-50 with iron ions in flotation pulp
Abstract
Hydroxamic acids have been recommended for wide use as reagents for quantitative and qualitative analysis of metals, their extraction separation, and as collectors in the processes of flotation beneficiation of ores of rare and non-ferrous metals. Owing to the simple technology of synthesis of alkylhydroxamic acids using aqueous solutions of hydroxylamine sulfate, the reagent IM-50, consisting of hydroxamic acids of the C₇–C₉ fraction or their sodium salts, has found application in concentration plants of the USSR. Studies of the effect of hydroxamic acids during flotation have shown that their interaction with iron ions present in the pulp volume and on the surface of minerals has a substantial and sometimes decisive effect on the results of beneficiation.
