FIELD: nonferrous hydrometallurgy. SUBSTANCE: invention relates to electrolytic production of tin from wastes and its refining. In order to enable reuse of tin, stannite electrolyte contains tin chloride, sodium hydroxide, water, and organic additive, in particular ethylenediamine-octyl bromide condensation product. EFFECT: reduced power and materials consumption, and improved quality of tin precipitates at higher rate of dissolution and precipitation of tin.
