Zusammenfassung:	Process for obtaining metal tin from RSn tin compounds in gaseous form, these being placed in an absorption tower in which they are neutralised and which has a wash circuit for hydrolysation and in which the solution formed at the base is recycled through a spray device and caused to fall onto on the RSn tin compound, the waste gases being delivered to the exterior, the solution being caused to be recycled through a tin recovery circuit which comprises an electronic recovery unit in which the RSn tin is removed by electrolysis of the tin dioxide SnO2.
