The basics of the original technology for the development of man-made placers in the south of the Russian Far East have been developed. The necessity of using methods of hydrodifluoride conversion, hydrometallurgy, fluoride autopsy is substantiated. To create an environmentally safe resource-saving technology for the enrichment of man-made formations, methods of powder metallurgy, leaching of raw materials by liquid extraction with simultaneous demercurization, as well as fluoride autopsy are used. The application of this scheme for extracting useful components from placer material will allow the industrial turnover of numerous man-made placers in compliance with resource-saving principles and without causing significant damage to the environment.
