The possibility of the Shalkiya deposit (Kazakhstan) flotation tailings processing with application of combination collector and water-air microemulsion generator was investigated. The combination collector consists of a mixture of composite aerofloat, thionocarbamate ТС-1000 and butyl xanthate in the ratio of 1 : 1 : 3. The proposed reagent is made up of two polar groups. In flotation process it can act as collector, being adsorbed on mineral surface and forming metal complexes with polar groups. In addition to this, apolar radicals flocculate slimed valuable components, thereby improving flotation process. Raw material for composite aerofloat production is mixture of alcohols С₃Н₇-С₆Н₁₃-ОН, recovered from dried alcoholic fraction of fusel-oil. In order to improve floatability of the Shalkiya deposit ore flotation tailings slimed particles of valuable components, an air micro-bubble generator was applied, providing for flotation reagent water-air emulsion. Application of combination collector, in comparison with standard regime, permits to increase lead mass fraction in concentrate by 5.0 %. Zinc recovery into rougher zinc concentrate is increased by 9.13 %. Besides, modified reagent consumption, if compared with standard collector, is decreased by 15–20 %. With joint application of combination collector and water-air microemulsion generator, lead mass fraction in rougher lead concentrate, in comparison with standard regime, is increased by 7.1 %, and recovery — by 5.83 %; zinc mass fraction in rougher zinc concentrate is increased by 3.8 %, recovery — by 14.13 %.
