FIELD: technological processes.
SUBSTANCE: method includes preparation of direct or reverse micelles with further reduction of metal precursors in them. Prior to preparation of micelles they are concentrated from water solutions by means of ion flotation or flotation extraction with application of surface agents and hydrocarbons. As water solutions artificial mixtures of dissolved water solutions are used, sewage waters, solutions of ores or their wastes that are poor in platinum metals, solutions of anode slimes of metals electrolytic cleaning.
EFFECT: preparation of platinum metals nanoparticles from wastes of mining industry; ores poor in platinum metals and sewage waters.
