MODIFIED REAGENT FOR FLOTATION OF NONFERROUS METAL ZINC-BEARING ORES Russian patent published in 2013 - IPC B03D1/02 B03D101/06 B03D103/02

Abstract RU 2496583 C1

FIELD: process engineering.

SUBSTANCE: invention relates to concentration of minerals, particularly to flotation of nonferrous metal zinc-bearings ores. Polymethylene napththalensulfonate is used as a modifying reagent for flotation of zinc-bearing ores of nonferrous metals. Said modifying reagent has common formula .

EFFECT: higher yield owing to higher depression in flotation and simplified concentration flow sheet.
