A pilot test of an aluminum electrolysis was completed in the year of 2014 using inert anodes with the composition NiFe2O4-M (M is metal). The volume of the cell is 110 × 66 × 79 cm, the size of inert anode is Φ34 × H22 cm, the total number of inert anodes in the cell are six, the current density of the inert anode is about 0.8 A/cm2, the total electrolysis current fluctuates from 2700 to 4000 A, the electrolysis duration time is 500 hours. The result of the pilot test indicated that the electrolysis process can be run successfully, since above inert anodes have better electric conductivity and corrosive resistance. In addition, none of the six inert anodes cracked during the whole electrolysis process even at the beginning of electrolysis when they were inserted in high temperature electrolyte. The main problem of pilot test is that the content of Fe as impurity is about 1.7% in the product, which is higher than the baseline value of GB/T. In order to remove Fe, related experiments are conducting continually.
