Title (EN) PROCESS FOR REDUCING AND RECLAIMING ELECTROLYTE CONTAINING TIN SALT
(FR) PROCEDE PERMETTANT DE REDUIRE ET DE REGENERER UN ELECTROLYTE CONTENANT UN SEL D'ETAIN
Abstract: front page image
(EN)Process for reclaiming stannous ion by reducing the same in an electrolyte to stannic ion through a simple operation in a short period of time, which comprises the steps of preparing the electrolyte in an acidic range as required and then adding metallic tin to the electrolyte and heating the mixture, in order to reduce the stannous ion oxidized in the electrolyte containing tin salt to obtain a stable electrolyte treated product. This process may be utilized particularly for effectively reducing and reclaiming an electrolyte which contains tin salt used for electrolytically coloring aluminum.
(FR)Procede permettant de regenerer un ion stanneux en reduisant celui-ci dans un electrolyte a un ion stannique par une operation simple dans une courte periode de temps, consistant a preparer l'electrolyte dans une plage acide comme requis et a ajouter ensuite de l'etain metallique a l'electrolyte et a chauffer le melange, de maniere a reduire l'ion stanneux oxyde dans l'electrolyte contenant un sel d'etain pour obtenir un produit stable traite au moyen de l'electrolyte. Ce procede peut etre utilise en particulier pour reduire et regenerer de maniere efficace un electrolyte contenant un sel d'etain utilise pour colorer l'aluminium par electrolyse.
