Ekeberg Prize 2020 Winner – Tantalum Recycling by Solvent Extraction
The winning paper for the 2020 Ekeberg Prize presents a method for recycling tantalum from capacitor scrap using an optimised solvent extraction process. The study provides a scalable approach to reclaim high-purity tantalum, contributing to circular economy objectives and reducing reliance on primary extraction.
