FIELD: gold mining. SUBSTANCE: invention, in particular, relates to processing obstinate antimony-containing gold-arsenic sulfide materials. Their processing consists in melting into slag and matte, removal of volatile sulfides with gases, and isolating gold into matte, which is evacuated. When being evacuated, matte is bathed with extracting phase consisted of lead or antimony metal. Process is carried out at temperature superior to melting temperature of matte. EFFECT: increased degree of recovery of precious components under single-step processing conditions and ensured environmental safety. 1 tbl
