FIELD: non-ferrous metallurgy, namely refining of noble metals.
SUBSTANCE: method comprises steps of heat treatment of charge including concentrate and reaction mixture containing aluminum powder and iron oxide at relation of concentrate mass to reaction mixture mass in range (1 : 1.1) - ( 1 : 1.4). Heat treatment is realized in inert gas medium. Refining of heat treated product is realized by leaching without separating product by metal and slag phase.
EFFECT: high degree of extracting metals of platinum group to chemically active forms.
