1. Способ рафинирования олова от мышьяка связыванием его в твердое нерастворимое соединение с железом и удаление кристаллов мышьяка с железом, например, центробежной фильтрацией расплава, отличающийся тем, что мышьяк связывают с атомами железа электролитическим анодным растворением его через диафрагму, пропитанной электролитом, и осаждения железа на обновляемом слое олова за счет его циркуляции, с последующим окислением пены до съемом.1. A method of refining tin from arsenic by binding it to a solid insoluble compound with iron and removing arsenic crystals with iron, for example, by centrifugal melt filtration, characterized in that the arsenic is bound to iron atoms by electrolytic anodic dissolution of it through a diaphragm impregnated with an electrolyte and precipitation of iron on the updated tin layer due to its circulation, followed by oxidation of the foam before removal. 2. Электролит для рафинирования олова от мышьяка по п. 1, отличающийся тем, что он содержит расплав хлоридов металлов при следующем соотношении компонентов: вес. %, калий хлористый 30-31; натрий хлористый 7-8; остальное железо двухлористое.2. The electrolyte for refining tin from arsenic according to claim 1, characterized in that it contains a molten metal chloride in the following ratio of components: weight. %, potassium chloride 30-31; sodium chloride 7-8; the rest is iron dichloride. 3. Электролизер для рафинирования олова от мышьяка для осуществления способа по п. 1, содержащий обогреваемую ванну для олова, электроды подвода постоянного тока, насос циркуляции олова, отличающийся тем, что в качестве анода использован железный цилиндр, помещенный в диафрагму пропитанную электролитом и соосно размещенную обечайку с зазором в ванне, в полость которой погружен насос для циркуляции олова по зазору с образованием оловянного катода для осаждения ионов железа.3. The electrolyzer for refining tin from arsenic for implementing the method according to claim 1, comprising a heated bath for tin, direct current supply electrodes, a tin circulation pump, characterized in that an iron cylinder placed in the diaphragm impregnated with an electrolyte and coaxially placed is used as an anode a shell with a gap in the bath, in the cavity of which a pump is immersed for circulation of tin along the gap with the formation of a tin cathode for the deposition of iron ions. 4. Электролизер для рафинирования олова от мышьяка по п. 3, отличающийся тем, что обечайка в нижней части снабжена участком перфорации для циркуляции олова, над которым с зазором подвешен анодный цилиндр в диафрагме, а в верхней части имеет горловину с меньшим диаметром с образованием кольцевого кармана, обеспечивающего постоянство пленки оловянного катода в зазоре.4. The electrolyzer for refining tin from arsenic according to claim 3, characterized in that the shell in the lower part is provided with a perforation section for circulating tin, over which the anode cylinder is suspended with a gap in the diaphragm, and in the upper part has a neck with a smaller diameter to form an annular a pocket ensuring constancy of the tin cathode film in the gap.
