The INTMET approach represents a unique technological breakthrough to overcome the limitations related to difficult low grade and complex ores to achieve high efficient recovery of valuable metals (Cu, Zn, Pb, Ag) and CRM (Co, In, Sb). Main objective of INTMET is applying on-site mine-to-metal hydroprocessing of the produced concentrates enhancing substantially raw materials efficiency thanks to increase Cu+Zn+Pb recovery over 60% vs. existing selective flotation. 3 innovative hydrometallurgical processes (atmospheric, pressure and bioleaching), and novel more effective metals extraction techniques (e.g. Cu/Zn-SX-EW, chloride media, MSA, etc) will be developed and tested at relevant environment aiming to maximise metal recovery yield and minimising energy consumption and environmental footprint. Additionally secondary materials like tailings and metallurgical wastes will be tested as well for metals recovery and sulphur valorisation. The technical, environmental and economic feasibility of the entire approaches will be evaluated to ensure a real business solution of the integrated INTMET process. INTMET will be economically viable thanks to diversification of products (Cu, Zn, Pb), high-profitable solution (producing commodities not concentrates), with lower operation and environmental costs (on-site hydroprocessing will avoid transport to smelters) and allowing mine-life extension developing a new business-model concept based on high efficient recovery of complex ores that will ensure EU mining industry competitiveness and employment. INTMET is fully aligned with EIP-RM validated in the PolymetOre Commitment where most of INTMET partners take part on and the market up-take solutions are guaranteed by an exploitation from industrially-driven consortia composed by 3 Mines, 2 SMEs (AGQ -waste&water tech provider; MINPOL -policy & exploitation expert), 2 tech providers (OUTOTEC and TR) and 5 complementary RTD´s with expertise in leaching and recovery metals processing

METGROW+ will address and solve bottlenecks in the European raw materials supply by developing innovative metallurgical technologies for unlocking the use of potential domestic raw materials. The METGROW+ consortium has received an EIP RM Commitment status. The consortium is supported by internationally respected research institutes and universities. Many of the partners (9) are members of EIT KIC Raw Materials consortium as well. The value chain and business models for metal recovery from low grade ores and wastes are carefully looked after. Within this project, both primary and secondary materials are studied as potential metal resources. Economically important nickel-cobalt deposits and low grade polymetallic wastes, iron containing sludges (goethite, jarosite etc.) which are currently not yet being exploited due to technical bottlenecks, are in focus. Concurrently, METGROW+ targets innovative hydrometallurgical processes to extract important metals including Ni, Cu, Zn, Co, In, Ga, Ge from low grade ores in a cost-effective way. In addition a toolbox for metallurgical system is created in the project using new methods and combinations. The unused potential of metal containing fine grained industrial residues are evaluated, while hybrid and flexible hydrometallurgical processes and treatment methods of fines are developed for both materials. Training and education of new professionals are facilitated within the METGROW+ project. The knowledge of raw materials and sustainable technologies will attract new talents in the field who can flexibly change fields from treatment of secondary to primary resources, which also smoothens the economic ups and downs in the primary sector.

Global Manganese-alloys (Mn) are highly linked to the steel sector for key engineering applications in Europe. In 2017, Mn-alloy production was approx. 4 Mio tons, required 12,200 GWh electrical energy and emitted around 14.2 Mio tons of CO2. Therefore, an energy intensive and inherent cross-sectorial value chain that is, nowadays, led by the Asian market demand. PREMA is an ambitious initiative that aims at demonstrating an innovative suite of technologies (involving heat recovery and solar technologic approaches) that allow to pre-treat Mn ores, utilising more efficiently energy and material streams and decreasing direct and indirect CO2 emissions (along with SO2 and NOx). LCA and LCCA methodologies will be implemented from early stages to ensure the technical, economic and environmental viability of the solution across the whole Mn-alloys’ value chain. The vision of PREMA is thus to make the Mn-alloys sector in Europe more flexible, sustainable and attractive. In order to cover the whole value chain, there is a strong presence of South African (SA) partners in the consortium, SA being the top 1 in high quality Mn ores’ extraction and exports worldwide. A win-win situation in order to strengthen the Mn-alloys and steel value chains in Europe. PREMA consortium puts together a total of 11 production facilities spread over Europe and SA among 4 Mn producers, representing an aggregated process capacity of 380 MW (Transalloys in SA, Eramet in France and Norway, Ferroglobe in Norway and Spain and OFZ in Slovakia). The innovative character of the project is brought by major players in R&D across Europe and SA, with the Norwegian organisation SINTEF as coordinator. Last but not least, clustering with other EU initiatives, including other SPIRE projects, will be paid special attention in order to create awareness of the project developments from early stages of the demonstration.

Unlike China, Russia or South Africa, the EU-28 Member States are not in the fortunate position of having vast, easily accessible ore deposits containing valuable metals. However, Europe does have large quantities of secondary industrial residues (tailings, sludges, slags and ashes) that contain sig¬nificant concentrations of both critical and economically important metals. The Euro¬pean Training Network for the Sustainable, zero-waste valorisation of critical-metal-containing industrial process residues (SOCRATES) targets ground-breaking metallurgical processes, incl. plasma-, bio-, solvo-, electro- and ionometallurgy, that can be integrated into environmentally friendly, zero-waste valorisation flow sheets. By unlocking the potential of these secondary raw materials, SOCRATES contributes to a more diversified and sustainable supply chain for critical metals (cf. Priority area 3 in EC Circular Economy Action Plan; COM(2015)614/2). The SOCRATES consortium brings together all the relevant stakeholders along the value chain, from metal extraction, to metal recovery, and to residual matrix valorisation in added-value applications, such as supplementary cementitious materials, inorganic polymers and catalysts. To maximise applicability, SOCRATES has selected four commonly available and chemically complementary residue families: (1) flotation tailings from primary Cu production, (2) Fe-rich sludges from Zn production, (3) fayalitic slags from non-ferrous metallurgy, and (4) bottom ashes from incineration plants. As a basis for a concerted effort to strengthen the EU’s critical-metal supply chain for Ge, In, Ga and Sb, SOCRATES trains 15 early-stage researchers (ESRs) in technological innovation: metal extraction (WP1), metal recovery (WP2), residual matrix valorisation (WP3) and integrated assessment (WP4). By training the ESRs in scientific, technical and soft skills, they are the next generation of highly employable scientists and engineers in the raw-materials sector.
