FIELD: mining.
SUBSTANCE: method of flotation concentration of lead-zinc ores includes ore preparation, bulk flotation followed by separation of lead-zinc concentrate. Prior to cycle of bulk flotation, preliminary lead flotation is carried out to produce lead concentrate and flotation tail. Bulk flotation is carried out with addition of butyl xanthate and diesel fuel in ratio of 1:1.5. Obtained bulk concentrate is treated with Ochrobactrum anthropi and Pseudomonas aeruginosa JCM 5962 bacteria in ratio OF 1:1 for 24 h.
EFFECT: increased efficiency of sulfide lead-zinc ores flotation process.
