Abstract
Generalization of the obtained materials leads to the conclusion that a significant amount of useful components has been accumulated in the man-made placers of Primorye (south of the Russian Far East), at the same time they pose a considerable threat to the environment. Using the example of the gold mining dumps of the Fadeevsky node, ways to solve this problem are outlined. The essence of the new approach is to implement a scheme of rational environmental management, which allows: 1- to recover precious metals (Au, platinum group elements) and demercurize man-made placers by liquid extraction from thiocarbamide leaching solutions; 2- to obtain raw materials for non-traditional industries in gold mining (powder metallurgy, titanium production, road and civil engineering). The involvement of manmade placers in the production sector will have a beneficial effect on the environmental situation in densely populated areas, and will also contribute to meeting the growing needs of the region for precious metals.
