On the base of literature survey and comparison of character of flotoreagents interaction with surface of sulfide minerals, structures and necessary functional groups of synthesized flotoreagents were theoretical predicted, having both collective and foaming properties, these are one strongly polar group, one cyclic low polar and nonpolar radical with linear structure. New sulfhydryl foaming agent (КСК-6) of tetrahydropyranic series from crude oil was obtained. Colloidal-chemical characteristics of КСК-6 in comparison with butyl xanthogenate were studied. Researches on replacement of Т-80 foaming agent by new reagent КСК-6 for flotation of monominerals and polymetallic ore were realized. It was shown, that action of КСК-6 is more effective in comparison with Т-80, besides, КСК-6 possesses also collective properties. Usage of KCK-6 foaming agent, treated with ultrasound, increases copper extraction to collective copper-lead concentrate by 5%, compared with T-80, lead extraction increases by 9%. Consumption of butyl xanthogenate decreases by 30%.
