APPLICATION OF NEW COLLECTORS IN FLOTATION OF COPPER-LEAD-ZINC ORE FROM THE TISHINSKY DEPOSIT

Abstract

The work is devoted to improving the technology of flotation enrichment of copper-lead-zinc ore of the Tishinsky deposit based on the development and research of new flotation reagents. It has been shown that increasing the efficiency of separation of sulfide minerals is an important factor in the rational use of mineral resources and improving the technical and economic performance of processing polymetallic raw materials. The aim of this study was to synthesize and evaluate the potential of new surfactants as collectors in the flotation of copper-lead-zinc ore. Alkylated diethanolamines and their dithiocarbamate derivatives were used as the subjects of the study. N-nonyl-N,N-di(2-hydroxyethyl)amine and disodium salt of N-nonyl-N,N-bis(2-xanthateethyl)amine were synthesized. The resulting reagents were found to be useful in copper-lead-zinc ore flotation processes, offering potential for increased selectivity and recovery of valuable components.
