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

过程脱碳、原材料稀缺、欧洲对关键资源的独立、工业废物的增值都是欧盟冶金工业面临的关键和强大挑战，在未来几十年里，为了保持可持续发展，同时保持其经济竞争力，欧盟冶金工业将不得不应对这些挑战。锰（Mn）和锰铁合金行业尤其如此。在开发低碳足迹、低能耗、无固体废物产生、采矿和冶金行业二次原料增值的可持续工艺方面，HAlMan代表了冶金行业的游戏规则改变者。HAlMan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，从锰矿石和含锰废物中生产锰金属和锰合金。由于冶金过程在二氧化碳排放中所占的份额很大，因此冶金工业的脱碳对欧洲金属生产的运作至关重要。HAlMan创新工艺的好处将超越Mn和Mn铁合金行业，它在循环经济中提出了独特的跨部门方法，其中：•含铝的渣滓/废料和锰铁工业的废物被增值，直接为铝和钢铁工业生产新的铝锰母合金•冶金级氧化铝（铝生产的原料，几乎完全由铝土矿生产，这是欧盟的CRM）是通过零碳足迹过程生产的•关键原材料的提取，包括稀土，从氧化铝生产过程的副产品将被展示•锰氧化物的生产和锂离子电池应用的电池制造将被展示。此外，HAlMan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。将进行生命周期评估、业务发展、传播和交流方面的重要活动。没有公开描述

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
