Аннотация: The study subject is lead-zinc sulphide ore with the predominant content of lead. The authors illustrate the efficiency of separating lead "head" under nonchemical treatment. Without collecting agents, during the f rst 6 mines of flotation, owing to the natural hydrophobic behavior of galena, it is possible to extract more than 40%Показать полностьюof the metal into a product with the lead content of 34.5%. Middlings contain almost 93% of zinc in this case. The lead and zinc ratio in the product is 1 to 1, which is favorable for bulk-selective flotation. The authors investigate Cytec Industries reagents: Aero 400; Aero 5745 and Aero 8045 as well as an apolar reagent as an additive. It has been found that the combination of Aero 5745 and butyl xanthate at a ratio of 1:1 provides the noticeable improvement of beneficiation data. It is found that addition of engine oil in flotation enables reduction in metal loss in the tailings by 1.5-2%. The flowsheet and the reagent regime are proposed for the bulk flotation cycle. The flowsheet ensures favorable conditions for the further selective extraction of a bulk concentrate and for the low loss of lead and zinc in the bulk flotation cycle tailings (6.25 and 9.12%, respectively).
