Yubileynoe deposit, which is situated on the eastern slope of South Ural, is one of the prospective sources in Ural region. Science and Production Association "RIVS" held the research works on five technological tests of copper and copper-zinc ores of the deposit. The concentration technology of these ores was developed and successfully mastered after the research of ore material composition and release of minerals. The copper concentrate (20 % of copper with the extraction of 90,2 %) was obtained according to the developed concentration technology of the deposit copper ores, containing 2,95% of copper and 0,49 % of zinc. The copper concentrate (17,9 % of copper with the extraction of 87,7 %), and zinc concentrate (52,2 % of zinc with the extraction of 69,9 %) were obtained from the copper-zinc ores, which contain 2,82 % of copper and 3,09 % of zinc. The developed technological regulations on the concentration of copper and copper-zinc ores of the deposit are the basis of the feasibility study. These regulations were used for the preparation of the equipment design of new Khaibiullin processing plant, using the equipment of Science and Production Association "RIVS": the flotation machines DRF 25, DRF 8,5, and the contact agitators CA-100 (КЧ-100). The productivity of new enterprise for the initial phase is estimated for 1,5 mln. t of ore per year. Nowadays, there is being planned the startup of the second line, which makes it possible to increase the productivity twice, and, at the same time, to process the copper and copper-zinc ores. The laboratory researches and updating into the developed technological scheme were held on the currently extracted ores. According to the research results, the copper concentrate (20,24 % of copper with the extraction of 88,8 %) and zinc concentrate (49,68 % of zinc with the extraction of 68,9 %) were obtained from the currently extracted copper-zinc ores, which contain 2,45 % of copper and 1,61 % of zinc.
