Novel electrolytic extraction process to release metals in non-treatable waste and economically unviable minerals

Reference number
Coordinator SWEREA MEFOS AB - Avdelning Processmetallurgi
Funding from Vinnova SEK 500 000
Project duration July 2015 - March 2016
Status Completed
Venture The strategic innovation programme for Swedish mining and metal producing industry - SIP Swedish Mining Innovation

Important results from the project

The aim of the project carried out was primary to explore the possibility of scaling up the new electrolytic treatment from lab-scale to pilot scale. A working equipment in pilot scale for smelting electrolysis and chlorination was developed and built within the project. Also, a working concept for the treatment of lead-containing glass has been identified and tested in practice.

Expected long term effects

The developed equipment will be used to conduct further studies of the technique of treatment of additional materials. The project has generated a considerable competence development for Swerea MEFOS in both electrolysis and chloride-based metallurgy.

Approach and implementation

Although the project suffered extensive delays due to late delivery of test equipment, work could be carried out in a satisfactory manner. A problem in the project has been an assumption in the application that turned out not to work in practice. A new approach has been developed and used in the project. Functioning equipment designed and developed within the project as well as a working concept has been identified and tested in practice. The project has generated a considerable competence within both electrolysis and chloride-based metallurgy.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
