IbD will create a holistic platform for facilitating process intensification in processes in which solids are an intrinsic part, the cornerstone of which will be an intensified-by-design (IbD). The IbD approach is hinged on the use of robust data about a process to redesign, modify, adapt and alter that process in a continuous, intensified system, and will be the new paradigm in the intensification of processes based on statistical, analytical and risk management methodologies in the design, development and processing of high quality safe and tailored chemicals, pharmaceuticals, minerals, ceramics, etc. under intensified processes. The IbD Project will deliver the EU process industry with an affordable and comprehensive devices-and-processes design-platform endeavoured to facilitate process intensification (PI), which specially targets -but is not limited to- solid materials processing. Five PI industry case studies will be implemented in mining, ceramics, pharmaceutical, non-ferrous metals and chemical processes using the IbD approach and to validate the IbD methodologies, tools, PI modules, control and fouling remediation strategies and the ICT Platform itself for the industrial implementation of PI in processes involving solids. The Platform includes design modules for the commonest intensified reactors-Rotating fluidized beds, micro-structured reactor and spinning disk, among others, as well as a generic Module Builder -equipped with a set of both proprietary and third-parties design tools- for designs carried out on the basis of radically novel ideas. The IbD Platform output is basically a data set that comprises the intensified reactor design -ready to be built or assembled-, an optimised whole process design including the upstream/downstream intensified unit operations and their solids handling capability, as well as cleaning methods, etc. and the expected economic and environmental quantitative impacts.

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 RTDs 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.

The vision of COCOP is that complex process-industry plants are optimally run by operators with the guidance of a coordinating, real-time optimisation system. COCOP will strengthen the global position of the European process industry, which represents 20 per cent of the European manufacturing base with around 450,000 companies generating 1.6 billion in turnover and 6.8 million jobs. The projects objective is to enable plant-wide monitoring and control by using the model-based, predictive, coordinating optimisation concept in integration with plants automation systems. This ambitious approach will be developed and verified in co-operation of European universities, research institutes and industry. The Consortium comprises two universities, three research organisations, the leading copper-plant technology provider, two large companies from the process industry (steel and special chemicals) and four SMEs providing automation solutions. Technical objective is to define, design and implement a concept that integrates existing industrial control systems with efficient data management and optimisation methods and provides means to monitor and control large industrial production processes. The plant-wide monitoring and control comprehend computationally intensive data analysis and large scale optimisation. The social objective is to improve operator plant-wide awareness and reduce mental workload. COCOP will liaise with standardisation bodies (automation) to ensure a sustained impact of the projects results. Commercialisation of the solution by its process-automation industry partners will allow plant operators to approach optimal production and result in reduced energy and resource consumption, and decreased on-site material handling time and greenhouse gas emissions.

MetalIntelligence proposes an EID in future efficient minerals analysis, processing and training. Transformational change caused by the third industrial revolution, which itself relies on extraction of raw materials, provides the impetus. A resource-efficient EU is recognised as a societal challenge. However, the pathway from searching for mineral deposits to metal production is complex and involves a number of sectors (geosciences, chemical analysts, mining, processing, metallurgy) that have tended to work in silos. Limited intersectoral collaboration has led to compartmentalised thinking which has become an impediment to improved resource and energy efficiency. The overall aim of MetalIntelligence is to disrupt this compartmentalisation, by training 6 ESRs through a multi-disciplinary network of academic and industry leaders with an exceptionally broad range of expertise and skills. The team comprises three beneficiaries (2 academic, in Ireland and Sweden, and one Industry, Finland) as well as 4 partners (from the UK, Ireland, and Finland) who will provide secondment opportunities and/or industrial supervision. The programme is arranged as work packages (WPs), including management, training, and dissemination as well as three research-driven packages. The first research-based WP aims to improve mineral analysis in preparation for more efficient processing. The second concerns itself with advanced modelling of dynamic minerals processing. The third will research modern, technology-enhanced training for future professionals. The tailor-made training programme consists of network wide components, delivered by industry and academia leaders as well as specific training in the workplace. The objectives of MetalIntelligence were designed to align with European innovation capacity policies and the network will contribute to keeping the industries competitive by developing innovative, more gender-balanced human capital for the raw materials sector in Europe.

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 significant concentrations of both critical and economically important metals. The European 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 EUs 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.
