有色金属工业减碳是工业过程减碳的重要抓手。本工作综述了有色金属工业碳排放现状和特点，在此基础上提出了有色金属工业尤其是重点冶炼行业的低碳技术路径。分析表明，铝冶炼行业是有色金属工业二氧化碳减排的核心，预计2025年有色金属工业将实现碳达峰，碳达峰时二氧化碳排放量为7.5亿吨；有色金属工业减碳技术路径主要包括清洁能源替代、发展先进的低碳技术与装备、金属再生利用及碳捕集利用(CCU)等，其中金属再生利用是有色金属工业支撑实现国家“双碳”目标的重要路径。

Reduction of carbon dioxide emission in the non-ferrous metal industry is critical for realizing the carbon peaking and carbon neutrality goals in China. State-of-the-art of carbon dioxide emissions in the non-ferrous metal industry were summarized and analyzed here. Based on this, the low-carbon technology path of non-ferrous metal industry, especially the key smelting industry, was put forward. The analysis shows that the aluminum smelting industry is the core of carbon dioxide emission reduction in the non-ferrous metal industry. It is expected that the non-ferrous metal industry will achieve a peak of carbon dioxide emission in 2025 with the peak value being 750 million tons carbon dioxide. The carbon dioxide reduction technology path of the non-ferrous industry mainly includes four parts, which are, green energy substitution, advanced low-carbon technologies and equipment, metal recycling, and carbon capture and utilization (CCU). Among them, metal recycling is the key path for the non-ferrous industry to support the realization of the national carbon peaking and carbon neutrality goals.
