Essentially sulfide, Russian copper–zinc ores are extremely rebellious owing to high mass fraction of pyrite reaching sometimes 85–90% and due to fine and nonuniform intergrowth of sulfide minerals with one the other and gangue. The main method to process sulfide copper-zinc ores is flotation. From the viewpoint of production of copper and zinc concentrates in the Ural Region, one of the promising deposits is Yubileynoe located on the east hillside of the South Urals. Copper and copper-zinc ore extracted from this deposit go for concentration at Khaibullinskaya Processing Plant and at a plant constructed by RIVS project and commissioned in 2011. The production procedures of Yubileynoe copper-zinc ore processing were developed based on core analysis. Copper-zinc ore entered the concentration process at times since 2011 and monthly starting from April 2015. In connection with this, RIVS accomplished adjustment of operating processes of copper–zinc ore flotation and undertook supervision of the technology developed for this processing plant. This article gives the recent figures on performance of the processing technology developed for copper–zinc ore extracted from 4–5 ore bodies within Yubileynoe deposit.
