摘要：
The article describes the non-frothing flotation data of monomineral fractions of tennantite, chalcopyrite and pyrite, measurements of electrokinetic potential of the phases, and the concentration control of butyl xanthate, sulfhydryl collector M-TF and hydrogen peroxide. The measurements of the electrokinetic potential and intensity of the characteristic UV bands reveal the influence of H2O2 concentration on the ion-molecular condition of the solutions of sulfhydryl collectors. It is found that butyl xanthate in the presence of hydrogen oxide fails to prove selective separation of tennantite and chalcopyrite from pyrite. M-TF ensures the contrast flotoactivity between copper and pyrite sulfides in softer treatment with H2O2. Hydrogen peroxide is recommended for scavenging of copper concentrate. Efficiency of H2O2 in recleaning of copper concentrate at a commercial scale is lower because of variable mineral composition of flotation feed.
