L’extraction des métaux précieux et non ferreux à partir de la matière première technogène de l’exploitation minière et métallurgique dans la région industrielle de Norilsk en Russie

Abstract

The largest technogenics deposits of platinum metals in the world are located in the Norilsk industrial region, made up over decades by the treatment of sulphide ores of copper-nickel of factory (Mining and Metallurgical Company Norilsk nickel – MMC NN). In MMC NN, over time, more than 300 million tons of tailings technogenics dry have been accumulated, which constitute a promising source of precious metals. It should be noted that all the major producers of MPG (the platinum group metals) in the world have deposits technogenics residues of various important factors, but the largest technogenics deposits of platinum are related only to the Russian sectors of mining and metallurgical. The necessity for the development of the Russian complex of metals of platinum and the strengthening of its position on the world market MPG is condition into the advisability of development a technology of processing of raw materials technogenics effective and safe for the environment.
