TECNALIA [TEC] has actively undertaken both the coordination tasks and the experimental activities that correspond to the solvometallurgical treatment of the received black masses. Firstly, the coordination of the project started with the preparation of the kick-off meeting, in which the entire Consortium assembled in San Sebastián (Basque Country – Spain) and comprises administration and management to ensure an efficient development of RHINOCEROS project.
Also, the experimental section concerning the critical materials extraction from the received black masses from spent batteries started out after receiving the samples from partners ACCUREC [ACC] and KIT.
After characterisation, TEC performed a first round of tests to these samples using a solvometallurgical route and assessing pre-treatment effect on the process. In parallel, State of Art is analysed for different relevant solvometallurgical systems aiming lithium recovery. New batches of experiments will be performed for process optimization and new tests will also be performed when further black mass samples are received.
