Tool and Workflow for Systematic Design of Reactive Extraction for Separation and Purification of Valuable Components

Rare-earth metals, such as La(III), Nd(III), Eu(III), or Y(III), which are recycled from electronic waste in urban mining, can be separated and purified utilizing reactive extraction. Process development equipment design then aim to determine the optimal extractant, diluent, any additional components, type, structure of internals, well all process parameters. This requires a deep understanding chemistry underlying complexing reactions engineering expertise on extraction-process design. To aid this task, tool was developed based cascaded option trees, combines both sciences. is supported by prototypic workflow systematically structured quantitative information thermodynamics. The method also applicable for extraction diluted components aqueous solutions, encountered fermentation broth context bioeconomy. will presented applied examples mining.
