FIELD: mineral concentration; applicable in metallurgical and chemical industries for foam flotation. SUBSTANCE: method includes preparation of pulp for subsequent flotation. In the course of pulp preparation, pulp is acted upon with reagents and exposed to ultraviolet radiation for 2-3 min and then during the entire process of flotation. EFFECT: higher selectivity of fixation of flotation reagents to mineral surface. 1 tbl, 1 ex
