What are the key technical and economic challenges in recovering critical metals from unconventional sources such as tailings, slags, and low-grade industrial residues? For waste streams, what challenges arise when integrating recycling streams into existing processing infrastructure? How can we address these challenges to make recovery more viable at scale? Are there successful case studies where unconventional sources have been transformed into reliable feedstocks?
