SUBSTANTIATION OF TECHNOLOGY OF MINING AND PROCESSING OF TECHNOGENIC RAW MATERIALS OF THE NOVO-TROITSKY TAILING DUMP

The current price situation for precious metals on the world market and a favorable exchange rate determine the prospect of increasing the production capacities of mining enterprises on the basis of involvement in the exploitation of reserves of gold-bearing natural and technogenic geo-resources [1-3]. In the South Ural region a number of technogenic formations have been formed in which raw materials are stored resulting from the processing of sufficiently valuable gold-bearing ores. Small volumes of individual waste storages, their fragmentation in space and the very uneven quality of mineral raw materials in individual objects, complete drainage as a result of long-term storage on the surface. The primary objects of the creation are environmentally hazardous storage, wastes from the processing of gold-arsenic ores. These include the tailings storage facility of Novo-Troitskaya concentrator, formed over 50 years ago. Small enough for passes stockpiled tailings and their location within the city limits of the city of Plast determine the need for early development of the blade of obtaining additional marketable products with the release areas under the social infrastructure. The article proposes an original method of geological assessment, which allowed creating a digital model of technogenic formation and calculating reserves with a justification for the development front of mining operations. The research of tailings processing technologies was carried out, the modes and parameters of technological processes were determined.
