Abstract
The paper discusses the analysis of the effect exerted by combinations of butyl xanthate and isobutyl dithiophosphate with isopropyl-O-N-methyl-thionocarbamate on monomineral pyrite and copper pyrite fractions. The list of the research methods includes nonfrothing flotation, adsorption, IR spectroscopy and ATR method, measurements of contact angles and induction times for air bubbles and thin section surfaces. The isobutyl dithiophosphate and thionocarbamate combination results in lower pyrite yield into concentrate of nonfrothing flotation, as well as in lower adsorption parameters and hydrophobic properties as compared with the butyl xanthate and thionocarbamate combination. Combining sulfhydryl ionized (strong) collectors with non-ionized (weak) collectors alters compositions of surface compounds of the collectors on sulfide minerals, which changes hydrophobic properties of the mineral surface and, as a consequence, raises flotation selectivity.
