FIELD: mining.
SUBSTANCE: invention relates to beneficiation of minerals and can be most effectively used in processing sulphide lead-zinc ores. Method of flotation-and-magnetic concentration of lead-zinc ores involves grinding ore, collective flotation to obtain a collective lead-zinc concentrate and further selection for lead and zinc concentrates using high-gradient magnetic separation. Recolouring collective lead-zinc concentrate to 100 % - 44 mcm and adding liquid glass in amount of 600–700 g/t before high-gradient magnetic separation.
EFFECT: technical result is higher efficiency and environmental safety of the process of beneficiation of sulphide lead-zinc ores.
