(54) METHOD OF MINERAL FLOTATION
(57)
FIELD: mineral flotation. SUBSTANCE: method may be used in processing of metallic and nonmetalloferrous materials and treatment of industrial sewage water. The method includes conditioning of initial raw material in pulp with reagents, pulp aeration with flotation size bubbles, treatment of pulp with sound vibrations, flotation to obtain concentrate. Pulp is treated with pulses of sound vibrations with frequency band given in the invention description. Pulse duration of sound vibration is from 2 to 4 periods of bubble natural surface-mode waves. Increased selectivity in recovery of useful component and increased quality of obtained concentrate is due to engagement of wider range of bubble sizes in their sound vibration treatment discharge of flotated particles, barren rock from bubble surface. EFFECT: higher efficiency. 1 dwg
