FIELD: electric arc metallurgy. SUBSTANCE: method involves melting by means of alternating-current direct single-phase electric arc of cassiterite pellets with slag-forming additions in graphite crucible or crystallizer; providing slag bath; spilling ground graphite onto bath surface; converting process into electrolytic mode; reducing tin in slag solution by directing electric current; for converting to electrolytic reduction process, providing normal short-circuiting of upper electrode onto graphite layer for retaining of current type. Method is suitable for producing of alloys used as solders and alloy additions. EFFECT: increased tin melting rates and improved purity of product without performing following refining processes. 1 dwg, 4 tbl
