Abstract
A mixture of stannic and chloride ions having a chloride to tin ratio of at least 4:1 (e.g., stannic anion complexes) is provided to the cathode compartment of an electrolysis cell in which the anode and cathode compartments are separated by a cationic permselective membrane. The anolyte is a mineral acid or tin salt thereof. Operation of the electrolysis cell results in the production of stannous anion complexes which may be treated to obtain stannous chloride products.
