Sustainable Mining and Metallurgy

This paper analyzed the current situation of carbon emission in nonferrous metal industry, pointed out that carbon emission mainly occurred in smelting process, especially in aluminum smelting process, and put forward three main ways to realize carbon neutralization: using clean energy, improving energy utilization rate and developing CCUS technology. Among them, hydrogen energy was the preferred clean energy for nonferrous metal industry; The improvement of energy utilization can be achieved by developing new processes and eliminating backward processes, improving the design and manufacturing level of key equipment, and developing thermal energy cascade utilization technology. The nonferrous metal industry should intensify its layout to ensure that carbon neutrality targets at all stages were achieved on schedule.
