Novel electrolytic extraction process to release metals in non-treatable waste and economically unviable minerals
|Coordinator||SWEREA MEFOS AB - Avdelning Processmetallurgi|
|Funding from Vinnova||SEK 500 000|
|Project duration||July 2015 - March 2016|
|Venture||The strategic innovation programme for Swedish mining and metal producing industry - SIP Swedish Mining Innovation|
Purpose and goal
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.
Results and expected 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.
