ION4RAW at the 2021 SIM exhibition

ION4RAW was present during the 70th edition of the annual Congress-Exposition of the Mineral Industry Society (SIM) in Lille (North of France).

The event, which took place from the 19th to the 22nd of October 2021, gathered 340 professional exhibitors as well as over 400 visitors. It brought together miners, extractive industry operators, stakeholders, R&D researchers and civil society (journalists and NGO’s). For ION4RAW partners, it was a great chance to present the project as well as to learn from other innovative initiatives.

Indeed, on the 21ST of October, the French’s Public Institution for Earth Science applications, the Geological Survey (Bureau de recherches géologiques et minières – BRGM) presented a technical conference on the mineral industry. Hosted by its Regional Director Isabelle Duhamel-Achin, it discussed challenges around critical raw materials (CMRs) in France and Europe, as well as the resilience of the mineral industry after the pandemic. For three days, the BRGM also held an exposition booth. Finally, an abstract of Mines & Carrières’ Special Issue has been presented.

2 years after the start of the project, the ION4RAW consortium gathered for a Circular Value Proposition Design Workshop

A mid-project reunion

Two years after the project’s start, the ION4RAW partners gathered for an online mid-project meeting, in order to present their achievements and share on the progress made.

This online gathering was also the opportunity for partners to reflect upon the exploitation of project results beyond the lifespan of the project. In H2020 projects such as ION4RAW, setting out a plan to ensure that the project results and their impact are maximised is key to ensure market uptake and the sustainable use of the innovations that have been developped.

Going circular with a Circular Value Proposition Design workshop

Inspired by the Ellen Mac Arthur Foundation, the LGI team designed and facilitated a virtual Circular Value Proposition Design workshop to help bring a systems and circular economy perspective to the project.

Partners imagined circular opportunities along the whole value chain, stepped into their potential future customers’ shoes and brought insightful, multidisciplinary perspectives into the discussions. The next step will be to co-develop a Circular Business Model for the project.

ION4RAW is now featured on the RMIS Platform

ION4RAW is now part of the EU-funded project to be featured on the RMIS platform. What does this mean? Why is it important? Let’s find out!

What is the RMIS Platform?

The European Commission’s Raw Materials Information System (RMIS) is developed by the Directorate-General (DG) Joint Research Centre (JRC) in cooperation with the DG for Internal Market, Industry, Entrepreneurship and SMEs (GROWTH). The RMIS is the Commission’s reference web-based knowledge platform on non-fuel, non-agricultural raw materials from primary and secondary sources.

As stressed in the 2008 European Union (EU) Raw Materials Initiative (RMI) and further recognised by the Strategic Implementation Plan (SIP) of the European Innovation Partnership (EIP) on raw materials (EIP-SIP), raw materials are essential for the sustainable and sound functioning of Europe’s industries. The EC is committed to promote the competitiveness of industries related to raw materials. These industries play important roles in many downstream sectors in Europe, such as construction, defence, chemicals, automotive, aerospace, machinery, equipment and renewable energy devices. Securing undistorted access to raw materials – in particular, critical raw materials (CRM) – is crucial to stimulate investment in innovation and new technologies.

In that context, the RMIS provides a structured repository of knowledge related to non-fuel, non-agricultural raw materials from primary and secondary sources. The overarching goal of the RMIS is to facilitate:

  • the availability, coherence and quality of knowledge required by specific EU raw materials policies and EC services;
  • access to key raw materials information from knowledge bases within and beyond Europe.

Specific parts of the RMIS support access to in-depth knowledge on the topics most relevant to the European and International raw materials context, such as Critical Raw Materials (CRM), secondary raw materials (SRM), economics and trade, and stocks and flows of raw materials, as well as analyses of aspects of environmental and social sustainability related to raw materials.

With the aim of establishing a continuous exchange of knowledge with national, EU-level and global knowledge providers, the RMIS includes the ‘Raw materials knowledge gateway’, which is a virtual space for providers for consolidating, expanding and increasing the visibility of raw materials-related knowledge.

ION4RAW on the Platfom

Several EU-funded projects related to raw materials are featured on the RMIS platform to advertise their work and findings. ION4RAW is now part of them, thus enabling a wider exposure for the project and its results within the European raw materials community.

To access it, click on the “European Level” Button, then “EU funded project” and select ION4RAW from the dropdown list. The ION4RAW page presents an overview of the project and its activities. It includes details about the work conducted within each work package as well as highlights from the work that has already been completed.

Discover the first ION4RAW public results

The ION4RAW project is progressing and its first publics results are now available. Discover the upcoming “Mapping of by-product potential in mineral deposits” and “Technical note and methodology guide for sampling and sample preparation” conducted by BRGM.

Evaluating by-products potential

These first public results of the project are part of Work Package 2, which is in charge of displaying an extensive and comprehensive evaluation of by-products potential – Bismuth, Germanium, Indium, Cobalt, Platinium and Antomony – in Gold-Silver, Copper and Copper-Gold deposits. Increasing knowledge by compiling data on the by-product’s concentrations and distribution in the EU ores, as well as mapping the location of the potential resources, are indeed keep-points to secure new potential European sources for the critical raw materials supply.

Indeed, reliability of supply in critical raw materials is one of the major challenges facing Europe. The availability of mineral resources is notably crucial for the deployment of low-carbon technologies and economic activities, in a context of climate change and global renewable energy policy, rapid growth of emerging economies as well as fast development of modern technologies that have led to a drastic upsurge in demand for a number of metals.

Mapping of by-products potential in mineral deposits

As ION4RAW aims to develop a new energy-, material- and cost-efficient mineral processing technology to recover by-products from primary sources, one of the first steps has been to produce a geographically-based compilation of the by-product occurrences and potential in Europe, in the form of a “Mapping of by-products potential in mineral deposits” conducted by BRGM. It compiles 1400 identified European occurrences for Cu, Au, Ag and Pb-Zn main commodities. This inventory allows economical assessment of potential resources as well as assessment of metallogenic processes related to these critical raw material endowments.

Figure 1. Distribution of the identified EU occurrences (n = 1400) showing identified ION4RAW targeted by-products classified according to their metallogenic family.

However, due to the heterogeneity of the existing databases and available knowledge on the entire European deposits and occurrences, a predictive assessment was performed for targeted elements, as they are not usually and/or automatically identified and/or (historically) assessed. To do so, the DataBase Querying DBQ approach (developed by the BRGM) was applied to the entire European dataset and allowed the determination of several areas of great interest for the prospection of the targeted by-products of the project. It allows potential identification of commodities, which are either rarely reported in analyses or through divers’ permit/deposit reports by mining companies. These areas can also be studied to identify major mine sites that might be interested in applying the mineral process, which would be developed through the study. For Peru, a compilation has been initiated with partners and offers a great dataset of the sites, which might be of great interested when it comes to the application of the process developed through ION4RAW.

A technical note and methodology guide for sampling and sample preparation

Alongside the “Mapping of by-products potential in mineral deposits”, a second deliverable has been produced as part of ION4RAW’s Work Package 2, where the sampling operations of the ores and pre-treatment steps before analysis are notably described.

Five deposits were selected for the project. Indeed, the ION4RAW process has to be tested on different samples as ionometallurgy is mineral specific. A detailed understanding of the mineralogy of the ores is therefore required to determine optimum processing routes for the product and by-product commodities.

The technical note and methodology guide presents the protocol for sampling and sample pre-treatment implemented in WP2 to be representative of the by-products that are naturally scattered in the ore rocks.

For each of the deposits, the report provides a deposit description (geographic, geologic and reserves), a description of the sampling operations for the ION4RAW project, and a pre-treatment chart to detail the sequence of the physical preparation steps required before analytical procedure. Sampling and preparation steps are essential to guarantee a reliable and valid analytical result.

WATCH: Our Mineral Processing Team Process Two Separate Concentrates at the Same Time


Our Mineral Processing Team is currently undertaking work as part of the Ion4Raw project, which is a European Union – Horizon 2020 funded project looking at the cost-effective recovery of by-products from primary sources.

As part of the study, a team in our laboratory in Truro, Cornwall, are processing samples containing both base and precious metals from a variety of sources in order to generate samples of concentrates for further testing using Deep Eutectic Solvent (DES) technology.

This current campaign is looking at the treatment of approximately 2.7 tonnes of polymetallic ore (Cu-Pb-Zn) from a Peruvian mine and involves the recovery of all three metals to recover two separate concentrate; copper + lead and zinc.

“In undertaking this work, we are using our existing pilot testing equipment in combination with various pieces of laboratory equipment which have been repurposed to operate on a continuous basis, specifically for this programme of work.” Says Associate Director, Ben Simpson. “In doing so, this is the first time that we have attempted to process two separate concentrates at the same time using our pilot plant and represents a key development in the capabilities that Wardell Armstrong is able to offer both to our research partners and commercial clients.”

Our expertise, combined with the mineral processing pilot plant facilities, is not commonly available in Europe and Wardell Armstrong is now firmly established as a centre of excellence and in high demand – not only by our current industrial clients but by research consortia across Europe. By participating in these high profile, multi Partner, multi-national research projects we can keep at the forefront of technological advances and remain the Partner of choice for many mining clients.
