STABLE ANODES INCLUDING IRON OXIDE AND IMPLEMENTATION OF SUCH ANODES IN ELECTROLYTIC CELLS FOR METAL PRODUCTION Russian patent published in 2009 - IPC C25C3/06 C25C3/12 

FIELD: metallurgy, electrolysis.

SUBSTANCE: invention refers to method of aluminium production by electrolysis and to anodes for aluminium production by electrolysis. The method of aluminium production consists in transmitting current between a stable anode and cathode through a bath containing electrolyte and aluminium oxide, wherein the anode is made of material selected out of the group consisting of Fe₃O_4, Fe₂O_3, FeO and their mixtures, in essence, the anode contains at least 90 wt % of Fe₃O_4. During the process of electrolytic production of aluminium anodes stay stable at controlled temperature of the bath of the electrolytic cell for aluminium production; also density of current transmitted through anodes is controlled over and production of commercially pure aluminium is facilitated.

EFFECT: production of commercially pure aluminium.
