近日，由中铝郑州有色金属研究院有限公司(以下简称“中铝郑州研究院”)牵头完成的“铝灰渣湿法全量化利用技术”取得重大突破，成功攻克我国铝冶炼等领域长期以来的铝灰渣处理难题。该技术不仅将铝灰中的有害物质进行完全无害化处理，还实现了资源的高效转化与再利用，经专家鉴定，总体技术水平达到国际领先。

中铝郑州研究院总经理、技术团队带头人刘万超介绍，在铝冶炼、铝再生及铝加工过程中，铝灰渣是不可避免的产物。我国铝灰渣年产生量超300万吨，由于其含有氮化铝、可溶盐及重金属等有害物质，环境风险高。自2021年被列入《国家危险废物名录》后，铝灰渣的处置利用愈发困难，非法处置事件时有发生，成为制约行业绿色发展的“瓶颈”。

面对这一挑战，中铝郑州研究院自2016年起，开启了长达近10年的科研攻关。团队聚焦铝灰渣无害化处理与资源化利用，经过大量研究试验和工程转化，成功研发出铝灰渣全量资源化利用技术，并逐步推广应用。

目前，该技术已在河南明泰科技发展有限公司、四川TCL海能环境科技有限公司等5家企业落地应用，年处理量达56万吨。其显著成效体现在多个方面：一是解决了铝灰渣中金属铝深度提取难题，残渣中金属铝含量低于2%;二是实现了有价组分的高效解离回收利用，氮化铝等活性组分水解率大于95%，释放的可燃气、氨气、氢气全部实现梯级回收利用，盐组分回收率大于98%;三是利用无害化高铝料制备的镁铝尖晶石、铝酸钙、铝酸钠等产品，完全满足相关标准要求。此外，该技术处理成本低，技术经济指标先进，已入选“河南省绿色低碳先进技术成果”，并被中国有色金属学会评选为“中国有色金属重大技术创新”。

该技术的成功研发与应用，不仅为企业解决了铝灰渣处理的难题，降低了环境风险，还通过资源回收利用创造了可观的经济效益。未来，随着该技术的进一步推广，有望推动我国铝行业向更加绿色、可持续的方向发展，为行业绿色转型提供有力支撑。
