FIELD: chemistry.
SUBSTANCE: invention relates to method of flotation dressing of sulphide copper-nickel ores, containing metals of platinum group, and can be used in collective flotation of sulphides from disseminated copper-nickel ores. Method includes crushing and conditioning of ore in presence of sulphhydryl collector -butyl potassium xanthate, introduction of foaming agent into flotation stage and isolation of nickel and copper sulphides into foam products, with waste rock minerals being separated into final tailings. Reagent B-56, representing polystyrylphosphinoxide of formula (C25H30O5P2)k, is introduced as foaming agent, with consumption 20 g/t.
EFFECT: increase of technological parameters of flotation process, extension of assortment of effective flotoreagents - foaming agents.
