Mining ores results in a bulk concentrate which processing is complicated by existing technologies. The aim of this work is to study and develop a rational technology of processing of collective Cu-Pb-Zn concentrates, including pressure leaching and flotation stages, with the selective separation of copper, lead and zinc in commercial products. The paper presents the pressure leaching–flotation flowsheet allows processing to produce a bulk concentrate conditioned monoconcentrate relevant standard, suitable for further processing on the profile enterprises without changing existing technological schemes. For a rather complete separation of copper, lead and zinc, select optimal parameters of pressure leaching Cu-Pb-Zn concentrates and reagents for the subsequent flotation. The distribution of metals in the technological scheme: rare (selenium, tellurium) and precious (gold, silver).
