Carbon Dioxide as a Sustainable Reagent in Circular Hydrometallurgy
ChemSusChem, Volume 18, Issue 3, February 1, 2025.Carbon dioxide is a useful reagent in hydrometallurgy and it can help to transform linear hydrometallurgical flowsheets into circular ones. Examples of applications of CO2 are pH control, the regeneration of acids used as lixiviants, or as a reagent for precipitation of metal carbonates. A new development is the solvent‐extraction‐assisted formation of

ChemSusChem, Volume 17, Issue 20, October 21, 2024.Extensive reuse of deep eutectic solvent should be ensured when applied in the Li‐ion battery recycling process. In each key step of recycling, including metal dissolution, recovery, and DES regeneration, decomposition and consumption occur, hindering DES reuse and thus undermining the feasibility of the entire recycling process. Abstract Deep eutectic
