- Abstract
Dumped slag and dust products of Norilsk region technogenic deposits are a promising source of precious and nonferrous metals. Methods for concentrating precious and nonferrous metals in multicomponent samples of the bottom deposits of slag product storage ponds are studied. A method of adhesive flotation using tributyl phosphate and straw oil followed by the collective melting - sulfatization operation, including absorption extraction of rare platinoids and preparation of rich platinum-metal concentrates, are studied.
