On the physico-chemical features of the interaction of the complexing collector IM-50 with iron ions of the flotation pulp
Abstract
Hydroxamic acids were recommended to be widely used as reagents for quantitative and qualitative analysis of metals, their extraction isolation, as well as as collectors in the processes of flotation enrichment of ores of rare and non-ferrous metals. Due to the simple technology of synthesis of alkylhydroxamic acids using aqueous solutions of hydroxylamine sulfate, the IM-50 reagent consisting of hydroxamic acids of the C7—C9 fraction or their sodium salts was used in processing plants of the USSR. The study of the effect of hydroxamic acids during flotation has shown that their interaction with iron ions located in the pulp volume and on the surface of minerals has a significant and sometimes decisive effect on the results of enrichment.
