FIELD: metallurgy. SUBSTANCE: pulp or mother liquor obtained after separation of arsenic trisulfide precipitate is added to the initial solution. Then sulfide reagent (sodium sulfide, sodium hydrosulfide or theirs mixture) is added. Pulp is settled, and precipitate is filtered off. Output of process is 30 l solution / 1 l reactor volume / 1 h. Gas formation is excluded. EFFECT: improved method of extraction. 2 tbl
