DEVELOPMENT AND TESTING OF TECHNOLOGY FOR PROCESSING SANDS FROM THE DREDGE FIELD TEST SITE FOR EXTRACTING GOLD AND HEAVY MINERALS CONTAINING MAGNETIC PARTICLES

The state of mineral resources base of the world and Russia is analyzed. Two variants of the model of Russia’s innovative way of development on the basis of the best available technologies’ introduction (BAT) are considered. The conclusion is made that not only Russian resources, but also Russian technologies, specialists and equipment play an important role in the choice of the model of innovative way of development. The authors’ block-scheme of BAT implementation at a mining enterprise is presented. It consists of four blocks: 1) analytical and research; 2) economic and analytical; 3) implementation project development; 4) obtaining an integrated environmental permit and BAT implementation. Emphasis is made on the fact that new environmental standards are being currently developed for the permissible integrated environmental impact of industrial facilities, which by 01.01.2025 should comply with all mining enterprises in Russia. A specific case of the developed, patented and tested technology of processing sands from the dredge field test side of the Dzharmagatay deposit (Transbaikal region), which includes gravity-magnetic-flocculation-electrical methods of enrichment, combined with cyanide leaching of gold, is considered. The method refers to the best available technology, as it allows to achieve a high level of mineral resources use (integration and rationality), to reduce pollution of atmo-, hydro-, litho- and biosphere by emissions and discharges
