noble metals metallurgy, particularly, pyrometallurgical processing of raw materials and concentrates containing gold and silver. SUBSTANCE: method includes mixing of initial alloy with flux containing sodium carbonate, calcium oxide, glass; melting of mixture; blowing of melt with oxygen-containing gas; cooling and separation of produced refined alloy of noble metals and slag. Novelty consists in that added to composition of slag-forming flux is borax, and glass is used in the form of silicate glass. EFFECT: higher efficiency of process due to reduction of residual content of gold and silver in slag and increased content of oxides of nonferrous metals in slag. 3 tbl, 2 ex
