The collecting capacity of xanthate, dithiocarbamate and their combination was studied. The effect of activity with respect to the gas-liquid interface of derivative forms of reagents represented by physically sorbed forms of collector was considered. Flotation experiments of lead-zinc ore from the Gorevsky deposit showed an increase in flotation performance when using reagent combinations. The use of a collector with pronounced chemisorbable properties in combination with a reagent having surface-active properties towards the gas-liquid interface caused an increase in the recovery of useful component. It was determined that activity of the physical form of sorption affects the selectivity of lead and zinc recovery - as activity of the physically sorbed form of reagent decreases, the selectivity of recovery grows.
