In 2010-2011, the specialists from Science and Production Association "RIVS" held the technological audit of Gai Processing Plant and the development of technological regulations on the processing of ores of the current and prospective extraction of Gai deposit. During this audit, there have been held the analysis and estimation of the installed equipment and technological schemes of the main concentration redivisions, on the basis of which, there were defined the main directions of the reconstruction of the processing plant of Gai Mining and Processing Combine, including the following operations: there was developed the rational combination of the existing crushing powers of the main building, as well as the introduced and planned semi-self-crushing complexes to provide the feed size processing of the main bulk flotation and the ore capacities, approved by the prospective mining plan; there was defined the optimal technological scheme of the ore concentration of Gai deposit; there were defined the dimension types of the main flotation and auxiliary equipment and there was developed its optimum arranging scheme; there were formulated the basic modernization directions of the management system by the technological process on the processing plant, including the testing, control and automation of equipment, applied on all departments of the factory. According to the results of the aggregative technical and economic calculation, the payback period of all recommended measures will be 4.5 years. Nowadays, Science and Production Association "RIVS" realizes the reconstruction project of the processing plant of Gai Mining and Processing Combine. At the same time, there is held the assembly of new flotation equipment and the replacement of the worn-out aeration units.

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 RIF 25, RIF 8,5, and the contact agitators KCh-100 (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.
