ION4RAW at the French national network PROMETHEE

Our ION4RAW partner BRGM presented the ION4RAW process to French national experts during the Scientific days of the PROMETHEE network.

The French national network GDR PROMETHEE was created in 2016 in order to structure the French research on the hydrometallurgical processes for a better management of the non-energetic raw material from mining activities and recycling, and more especially low-grade resources. This network gathers 30 laboratories from the French National Centre for Scientific Research (CNRS), Atomic Energy Commission (CEA) and the Bureau of Geological and Mining Research (BRGM), partner of the ION4RAW project.

Scientific days are organized annually by the GdR PROMETHEE, and are open to researchers, engineers, PhD and pos-doctoral students from the academic and industry network, experts in the field of non-energetic raw material management.

This year, our ION4RAW partner BRGM seize the chance of having such a scientific pool of experts to present the ION4RAW project with a presentation « Premiers essais d’évaluation de la disponibilité des éléments traces CRM dans les minerais aurifères et cuprifères européens pour la récupération par ionométallurgie ». The presentation is available online here.

Attendees were interested to learn more on the hydroprocess and know the reagent tested for DES and lixiviation by WP4 but as it is confidential, they were invited to contact the coordinator of the project (Maria Tripiana from Idener) as well as Tecnalia and Sintef for available details and to follow the project newsletter and following publications.

Discussions with external stakeholders will follow this very fruitful event!

New scientific article published by BRGM!

As part of our ION4RAW project, the French’s Public Institution for Earth Science applications, the Geological Survey (Bureau de recherches géologiques et minières – BRGM) published an article proposing a new method to identify more accurately the accessible mineral resources: Predictive assessment of metallogenic signatures using the DataBase Querying (DBQ) method: A European application.

In the context of climate change and related international renewable-energy policy, the fast growth of emerging economies and the rapid development of new technologies have caused a drastic increase in the demand for several metals and other elements. Thus, a reliable supply of critical raw materials is one of the major European challenges in the deployment of low-carbon technologies and to secure several strategic sectors of European industries.

However, not all elements of economic interest today have been systematically assayed and/or studied in the past, and the existing European databases of are incomplete from a 2022 viewpoint. Among recently identified critical raw materials, several elements were, or are, not systematically identified and/or assessed in European databases, as their high economic importance and supply risk have only recently become apparent. Thus, a gap may exist between historical databases and current metal needs.

To adress this gap, BRMG developed a new approach in addition to a ‘classical’ application of the DataBase Querying (DBQ) geostatistical mineral prospectivity method. This new approach is based on the assessment of more global predictive metallogenic-signature aspects, by clustering studied elements known to occur in various metallogenic families, using ArcGIS software. Development of this method at a continental scale allowed identifying several areas of great interest in Europe for exploration of the targeted by-products.
