Application filed November Be it known that Axen s'rAN'riN' ESTELLE, of Sweden, residing at Hagen,- in"; phalia, Germany, have invented a new and useful Process of Electrolytically Proof which the'following is a fullclear, and exact descri tion. 'invention is directe to; th tion of iron by the electrolytic tion of a solution comprisinga' caustic alkali and a ferric hydrate.

tric current met'allic; iron ispreci itatedfo'n the cathode in form of asmoothlayer,-and oxygen is developed near the anode, wh' the hydroxid is g' duallydecompo'se In: order to render this process continuous, hydroxid may dded tothe'electrolyte in the electrolyzing tank or outside of it 11! ortion as metallic "iron Instead of iron hydroxid most other compounds of iron with oxygen and hydrogenmay be used. Iron compoundswith oxygen;

alone are less appropriate'for the process,- but by a previous carbonic alkali at may be rendered .fit
