Abstract

The article reports analytical data on surface compounds of galena, chalcopyrite and sphalerite. By X-ray photoelectron spectroscopy and IR spectroscopy, the authors find the oxidability series: PbS ≈ ZnS < CuFeS2. Sphalerite has the largest amount of free water in the surface layer. The frother and non-frother flotation experiments show that floatability of monomineral fraction of galena is higher in neutral medium at sulfhydryl agent concentration under 10-4 mole/l. In alkaline medium floatability of galena grows with increasing concentration of sulfhydryl agents, which degrades selectivity of flotation. Galena recovery is the highest with butyl xanthate and di-isobutyl di-thiophosphinate. Tests of adsorption use the method of isomolar series and non-frother flotation conditions. Constants of adsorption velocity are calculated at different ratios of strong (butyl xanthate) and weak (thionocarbamate) agents for galena, chalcopyrite and sphalerite. If thionocarbamate prevails, the adsorption velocity constant grows, and so does the recovery of chalcopyrite as against galena and sphalerite. The experimental results agree well with the production research data on samples from Stepnoe and Rubtsovsk polymetallic ore deposits.
