| Abstract Scope |
The recycling of by-products is a key discipline for future metal production. Slags, dusts, and sludges represent essential resources for the alternative extraction of metals. A crucial aspect of by-product recycling is the recovery of multiple metals from a single residue under CO₂-optimized conditions. Another requirement for future-relevant processes is a zero-waste approach that meets demands for landfill avoidance and maximum raw material utilization. Additionally, an energy-optimized concept is considered a fundamental requirement.
The "Green Zinc" project evaluates the recovery of zinc, lead, and specialty metals such as indium, germanium, and antimony, in collaboration with key global partners such as Glencore, Primetals, and Ecobat. The poster presents pioneering concepts in the use of hydrogen and bio-carbon, as well as energy-optimized "zero-waste" technologies for processing industrial residues in zinc, lead, and copper production. Economic aspects and the path toward industrial implementation are also discussed. |
