      <abstract xml:lang="ru">
        <p>Представлены результаты лабораторных исследований реагентов – пенообразователей производства «НПО ХИМТЭК», по селективно-коллективно-селективной схеме флотации богатых и медистых руд Талнахского и Октябрьского месторождений, перерабатываемых на Талнахской обогатительной фабрике. Проведенный эксперимент показал, что применение одного из образцов позволяет повысить извлечение меди в одноименный концентрат в среднем на 2,29 % без ухудшения его качественных характеристик.</p>

        <p>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.</p>
