Zusammenfassung:	A method and apparatus is described for electrolyzing a tin containing electrolyte, wherein an electric current is passed between an anode disposed solely in an aqueous anolyte and a cathode located solely in an aqueous-electrolyte immiscible catholyte comprising a halogenotin complex. This has utility including the separate recovery of elemental tin and an organic "onium" compound from the halogenotin complex whereas according to earlier specifications, an "onium" compound is used in only catalytic amounts and a complex formed from the onium compound is recovered after the organotin products have been separated. It has been found that the method of the invention can be operated at an attractively high and economical current density at relative low voltage.
