Main objectives of work package 1 – resource description and pretreatment steps are the description of resources selected for this study (primary and secondary resources from German Kupferschiefer, French polymetallic deposits containing Cu), and the development of eco-efficient technologies for pre-treatments before the bioleaching treatment.

WP 1 is led by UVR-FIA and contributions come from BRGM, HIF, GEOS, KGHM, MLU and TUBAF.

EcoMetals is a transnational research project aiming at the development of innovative biohydrometallurgical processes for the extraction of copper and other (associated) metals from coppershale.. The project receives funding from the French ANR (L’Agence nationale de la recherche) and the German Ministry of Education and Research BMBF (Bundesministerium für Bildung und Forschung) under the reference number 033RF001.

In total, 17 partners from science and industry collaborate in this project. Start of the project was in February 2014 and it will run until June 2017.
