Abstract
In Russia and abroad, the scope of the use of gold has significantly expanded, which undoubtedly affected the level of production. However, despite the fairly high rates of gold mining, the economic situation that has developed in recent years makes the companies look for new innovative placer processing technologies that will allow preserving and increasing the extraction of the precious metals. The search for and exploration of new placer gold deposits requires very considerable financial resources and time, and therefore the proposed project for the extraction of alluvial gold from technogenic deposits is of great importance for the functioning of the mining industry of the Irkutsk region, since it helps to overcome at least two negative trends: firstly, the deterioration of the mineral resource base, and secondly, large losses of gold with dump products (up to 50%) associated with the use of obsolete washing equipment. Modernization of production capacities and processing technologies is not only one of the main factors for increasing competitiveness in the gold mining industry and attracting investors, but will also help increasing the mineral resource base of the Irkutsk region by reassessing technogenic deposits, setting gold technogenic deposits on the balance, development of technologies for technogenic deposits and processing, and involvement of technogenic deposits in the mass processing.

Summary
Russia has obtained leading positions in gold mining and is an advantageous partner on the global gold market. The production of gold from mineral raw materials increased by 3% to 262.404 tons, and gold production from scrap decreased by 9% - to 35.014 tons. According to the Union of Manufacturers, the production of gold from mineral raw materials in Russia in 2017, as compared to 2016, will increase by 2-3% to 270 tons due to the development of existing capacities in such fields as Mayskoye and Albazinskoye. Sakha (Yakutia)), Ugakhane (PJSC Vysochaishy, the Irkutsk region), Ryabinovoye (PJSC “Seligdar”, Republic of Sakha (Yakutia)) and others. The growth of gold extraction and production was provided by the following regions of the Russian Federation: the Chukotka Autonomous District, the Magadan region, the Republic of Sakha (Yakutia) and the Republic of Buryatia, the Khabarovsk and Kamchatka.
