FIELD: enrichment of useful minerals. SUBSTANCE: base and control flotation of origin material is carried out to produce foam and chamber product. Chamber product is additionally ground, then its control flotation to produce concentrate and tails is carried out. Said grinding is carried out within 1-30 min in uninterrupted regime. The process takes place in spring mill, minimal rotation rate of operated organ being 2.0-40 m/s, ratio solid and liquid products being 2.0: 1.0-5.0: 1.0. Foam product of base flotation is additionally ground. The process takes place in spring mill. Concentrate of control flotation is affected by additional grinding followed by selection. EFFECT: improves efficiency of the method. 5 cl, 1 dwg
