Workpackage (WP) 1 was expected to function as the multistakeholder platform. In this WP, all of the key players have met and addressed the transversal issues of refractory metals. Managed by the consortium, it gathered experts from the three External Experts Committees: Policy/Society, Technology and Market.
This workpackage assessed the current and future selected metal needs of the European industry. It also examined to what extent these can be met with European and non-European sources, and explored innovative strategies for the improvement of the reliability and affordability of supply for metals and metal-based intermediate products. It has delivered guidelines, has defined indicators and has proposed (new) standards. This knowledge has been used to analyse the data collected and the innovation proposed in the four technical WPs.
The main objective of Workpackage 3 was to address the recovery of refractory metals in metallic or oxidic forms existing in waste (old mine tailings and industrial waste) and to reduce the amount of waste sent to landfill. To reach this main objective the following actions have been conducted in WP3:
Refractory metals (RM) – Tungsten, Tantalum, Rhenium, Molybdenum and Niobium – play a highly strategic role in European industrial sectors. Substitution analysis is a key concept that must be present in a transversal way to study and design the entire value chain. This Workpackage aimed to discuss and analyse the mapping of RM substitutes within their most relevant applications in EU industry according to the importance of three criteria: social, economic and strategic. This map had to be considered as part of the value chain analysis carried out in WP1, and a factor in the prioritisation and definition of clear actions in the fate of RM regarding supply, recycling/waste management strategies and loops.
Based on the evaluation of the primary resources of five refractory metals, the available and innovative mining technologies have been identified; the existing technologies of mineral processing and extractive metallurgy have been reviewed and the innovative technologies have been investigated; wastes including mineral processing tailings and metallurgical slags have been evaluated with specific attention given to the reduction of the amount of waste, environmental impacts, the recovery of valuable trace elements and potential uses as construction materials.
All of the information have been discussed and analysed during the workshops with the external experts.
The Workpackage 4 objectives included:
• the identification of existing recycling technologies and gaps to be addressed;
• the identification of barriers for the recycling of refractory metals;
• the determination of applications where recycling may present a significant opportunity.
