The object of the study is a collective concentrate, which was obtained by flotation of sulfide lead-zinc ore from an East Siberian deposit using a combination of diesel fuel and butyl xanthate. In the collective concentrate the main ore minerals are galena and sphalerite. Non-metallic minerals are quartz, dolomite, calcite and chlorite. In the work were studied various methods of preparing a collective concentrate for a flotation selective cycle: without pulp preparation, washing with sodium sulfide, temperature, ultrasound, and bacterial treatment of a collective concentrate. The results of studies of the flotation selective cycle showed that it is impossible without preparation. Satisfactory technological indicators were not obtained when applying twice washing with sodium sulfide and using ultrasound. Introduction to the flow sheet of the operation of steaming in a medium of sodium sulfide and dosing of activated carbon into the process made it possible to obtain a foam product (lead concentrate) with a lead content of 45%, but the recovery was ~ 43%. In addition, the process is environmentally unfavorable, characterized by high material and energy costs. The prospects of using the bacterial method for preparing collective concentrates using diesel fuel for the flotation selective cycle are shown. The bacterial method consists in treating the collective concentrate with the bacteria Ochrobactrum anthropi and Pseudomonas aeruginosa JCM 5962.

In this paper, based on the experiment on pure minerals, namely, galena, sphalerite and pyrite, it is concluded that the appropriate pH range for galena flotation is 8.5-10.5, that for sphalerite flotation is 7-10.5 and for pyrite is 2.5-6.5. For galena, sphalerite and pyrite, butyl xanthate has a better collecting performance than ammonium dibutyl dithiophosphate. Both Na2SO3 and ZnSO4 have a relatively weak inhibitory effect on galena. As for sphalerite, the mixing of Na2SO3 and ZnSO4 has a better inhibitory effect than when they are used alone, with the best inhibitory effect obtained when the proportion of Na2SO3 and ZnSO4 is 1:2 and their dosages are respectively 100mg/L and 200mg/L. In zinc flotation, CuSO4 demonstrates an apparent activating effect on the inhibited sphalerite with its appropriate dosage at 2*10 -4 mol/L. In actual separation and selection of ore, when the grades of lead, zinc and silver in cyanide tailings are respectively 2.41%, 3.77% and 272g/t, a fairly good index is obtained where the Pb concentrate is of a grade of 33.41% with its silver grade of 4051.57g/t and the grade of Zn concentrate is 59.67% with its silver grade of 798.08g/t.
