| Abstract Scope |
Rare-earth metals e.g. recycled from electronic waste in the context of urban mining can be separated and purified utilizing reactive extraction. Process design then aims at optimal selection of reactive extractant, diluent, possible additional components, as well as all process parameters. This requires a deep understanding of the CHEMISTRY of the underlying complexations as well as ENGINEERING expertise on extraction-process as well as equipment design.To solve this design task a tool was developed based on cascaded option trees, which combines the expertise from both sciences. Process design is on the one hand supported by a prototypic work flow and on the other hand by systematically structured and quantitative information on the underlying thermodynamics. The method is also applicable for extraction of diluted components from aqueous solutions as encountered in fermentation broth in the context of bio-economy. The method will be presented and applied to examples from urban mining. |
