FIELD: minerals dressing. SUBSTANCE: bulk copper-zinc pyrite-containing concentrate floatation separation method provides for conditioning of pulp in alkaline medium with zinc sulfides reactant-depressor, mixing with collecting reactant and foaming reactant, copper sulfides and pyrite extraction into foam product and production of zinc concentrate with the help of chamber process. Water soluble polyphosphate complexes of copper are introduced in pulp conditioning process as zinc sulfides depressor. EFFECT: improved quality of minerals dressing. 1 tbl
