The paper presents results of laboratory investigation of foaming agents produced by «NPO Khimtek» using a selective-collective-selective flotation circuit of high-grade ores and copper ores from the Talnakhskoye and Oktyabr’skoye Deposits, processed at the Talnakh Concentrating Mill. The experiment performed demonstrated that application of one of the samples allows enhancement of copper extraction into the copper concentrate by 2,29 % on average without deterioration of its quality.
