description metallurgy of noble metals. SUBSTANCE: method includes melting of concentrates with additives, oxidation and cooling of melt, separation of solidified products by their physical properties. Used as additives are products on base of aluminum oxides or grog, sodium carbonate, soda-lime glass or slag of refining of metals of platinum group on base of sodium and calcium silicates. Used as target product is heavy alloy separated from under layer of slag; components of melting charge are taken in the following ratio, mass-%: concentrate on base of ferrous oxide, 5 to 25; products on base of aluminum oxide or grog, 5 to 40; sodium carbonate, 5 to 10; soda-lime glass or slag of refining of metals of platinum group, remainder. EFFECT: reduced duration of cycle; reduced losses of noble metals; recovery of nobble metals from 97 to 99% at content of metals of platinum group in alloy from 20 to 35%. 4 ex
