Aim of sub-project:
As part of the process chain for the production of strategic metals highly complex leaching solutions are generated. They contain the project-relevant target metals Ge and In at extremely low concentrations in aqueous solution. The separation is a scientific and technical challenge. By use of membrane technology, the selective separation and concentration of the target metals should be investigated. Central objective, therefore, is to develop a method for providing a concentrate of the target metals and parallel of the accompanying elements.
As part of a process-synthesis, which is carried out in cooperation with the other project-partners, a ideally sustainable process should be derived.
Ongoing work and results:
Project is in progress.
