FIELD: metallurgy.SUBSTANCE: invention relates to concentration of minerals and can be used to increase the yield of valuable products, particularly, zinc and lead, by flotation. Proposed method comprises flotation, processing of pulp-bearing solution by pulse discharges and precipitation of solid phase. Processing of pulp-bearing solution is carried out by pulsed high-voltage discharges of specific energy of 8.6-11.2 kJ/dmfed directly into pipeline communicating flotation machine with settle-thickener. Action of pulsed high-voltage discharges is brought about provided that: R/R=10.4 where: R is the radius of efficient wave effects; Ris the spacing between electrodes and R.EFFECT: higher intensity and rate of deposition of disperse particles from foam after flotation.2 cl, 3 dwg, 1 tbl |
