Sustainable Hydrogen and Aluminothermic Reduction Process for Manganese, its alloys and Critical Raw Materials Production (HAlMan)

工艺脱碳、原材料稀缺、欧洲对关键资源的独立性、工业废物的价值化都是欧盟冶金行业面临的关键和严峻挑战，在未来几十年必须应对这些挑战，以保持其经济竞争力的同时保持可持续发展。这对于锰（Mn）和Mn铁合金工业尤其如此。哈尔曼代表了冶金行业的游戏规则改变者，因为它开发了低碳足迹，低能耗，无固体废物产生，采矿和冶金行业二次原材料增值的可持续工艺。哈尔曼将在TRL 7上展示一种综合工艺，通过使用氢和二次铝（Al）源作为还原剂，从锰矿和含锰废物中生产锰金属和锰合金。由于冶金过程在CO2排放中占有很大份额，因此冶金行业的脱碳对于欧洲的金属生产至关重要。哈尔曼创新工艺的好处将超越锰和锰铁合金行业，它在循环经济中提供了一种独特的跨部门方法，其中：·含铝浮渣/废料和锰铁工业的废料可直接用于生产铝和钢铁工业的新型Al-Mn中间合金（铝生产的原料，几乎完全由BENGINE生产，BENGINE是欧盟的CRM）是通过零碳足迹工艺生产的。将展示氧化铝生产过程中的副产品。将展示用于锂离子电池应用的氧化锰生产和电池制造。此外，哈尔曼项目研究从工艺气体中回收热量和氢气，以提高工艺经济性和产量。关于生命周期评估、业务发展、传播和交流的重要活动将在carried.no公开说明

Decarbonization of processes, scarcity of raw materials and Europe independence on key resources, valorisation of industrial waste are all key and strong challenges the EU metallurgy industry is facing and will have to deal with in the next decades to remain sustainable while keeping its economic competitiveness. This is particularly true for the manganese (Mn) & Mn ferroalloys industries. HAlMan represents a game changer in the metallurgical industry in view of developing sustainable processes with low carbon footprint, low energy consumption, no solid waste generation, valorisation of secondary raw materials from mining and metallurgical industry. HAlMan will demonstrate at TRL 7 an integrated process to produce Mn metal and Mn alloys from Mn ores and Mn-containing waste by using hydrogen and secondary aluminium (Al) sources as reductants. As metallurgical processes have large share in CO2 emission, decarbonization in metallurgical industry is essential to operate metal production in Europe. The benefits of the HAlMan innovative process will go beyond Mn and Mn Ferroalloys industries, and it presents a unique intersectoral approach in circular economy where: • Al-containing dross/ scrap, and waste from ferromanganese industry are valorised to produce directly new Al-Mn master alloys for Al and Steel industries • metallurgical grade alumina (the feedstock for Al production, produced almost exclusively from Bauxite which is a CRM for EU) is produced via a zero-carbon footprint process • the extraction of critical raw materials, including REEs, from the alumina production process by-products will be demonstrated • the production of manganese oxide and cell fabrication for lithium-ion battery applications will be demonstrated. Additionally, HAlMan project studies heat and hydrogen recovery from process gas to improve process economy and yield. Significant activities on Life cycle assessment, Business development, dissemination and communication will be carried.no public description
