The Aluminum Production Process is Optimized by Electrolysis Method
Electrolysis is a redox reaction under the action of an electric field. Preparation of aluminum by electrolysis is using molten sodium aluminum fluoride as a solvent, molten alumina as a solute, carbon as the anode, aluminum solution as the cathode, under the action of the electric field, the temperature is 950°C -970°C, the electrochemical reaction on the poles in the electrolytic cell: 2Al203==4Al302. Anode reaction: 2O2--4e-=02↑ cathode reaction: Al3+3e=Al o The main electrolytic product of the anode is C02 and CO, which may also contain small amounts of HF and parts of solid particulate matter. In order to improve the air quality and meet the emission standards, it is necessary to treat the anode production of the exhaust gas, which can only be discharged into the air before meeting the emission standards. The electrolysis product of the cathode is aluminum, which is purified and clarified in the thermal insulation furnace, cast into aluminum ingot or directly processed into wire billet and profile.
