Carbon Dioxide as a Sustainable Reagent in Circular Hydrometallurgy [PDF]
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
