| Abstract Scope |
Aluminum alloys find applications across diverse sectors, from household products to high-tech industries due to their lightweight properties, corrosion resistance, and formability. As the ultimate circular material, aluminum can be recycled indefinitely. However, repeated recycling accumulates impurities (Fe, Mn, Cu, Si, Mg), degrading scrap quality and value, while poor alloy sorting exacerbates contamination and restricts high-quality production. With automotive aluminum demand projected to quadruple by 2050, this could create a global 'scrap surplus' crisis dominated by low-value scraps. To address this, the development of advanced sorting and purification technologies is essential. In secondary aluminum alloys, Fe poses the most significant threat, forming detrimental β-AlFeSi intermetallic needles that impair mechanical properties. This study focuses on scaling up an innovative gravity sedimentation method for iron removal from aluminum scrap, based on bench-scale results. This work pinpoints implementation challenges and delivers scalable solutions for industrial adoption of the technology. |
