Sustainable Mining and Metallurgy

In the context of increasing global energy constraints and stricter environmental requirements, the aluminum electrolysis industry has come under widespread scrutiny due to its high energy consumption and carbon emissions. This paper systematically studied new energy-saving technologies for aluminum electrolysis cells, focusing on the principles and application of cathode phosphorous-iron casting technology, composite copper-inserted steel bar technology, self-balancing busbar technology，dual-side gas collection technology，new anode steel stubs, and prebaked anode slotting technology. These technologies have demonstrated significant potential in reducing energy consumption, with the lowest direct current consumption in aluminum electrolysis reaching 12200kWh/t-Al. The application of these technologies helps alleviate the energy-saving and carbon-reduction pressures faced by aluminum electrolysis production enterprises while enhancing production safety and stability.
