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

The present project is aimed to the development of a multi-step process for the production of second-generation biofuels from lignocellulosic biomass in a cost-efficient way through the use of tailored nanostructured catalysts. The proposed process is based on the cascade combination of three catalytic transformations: catalytic pyrolysis, intermediate deoxygenation and hydrodeoxygenation. The sequential coupling of catalytic steps will be an essential factor for achieving a progressive and controlled biomass deoxygenation, which is expected to lead to liquid biofuels with a chemical composition and properties similar to those of oil-derived fuels. According to this strategy, the best nanocatalytic system in each step will be selected to deal with the remarkable chemical complexity of lignocellulose pyrolysis products, as well as to optimize the bio-oil yield and properties. Since hydrodeoxygenation (HDO) is outlined in this scheme as the ultimate deoxygenation treatment, the overall hydrogen consumption should be strongly minimized, resulting in a significant improvement of the process economic profitability. The use of nanostructured catalysts will be the key tool for obtaining in each chemical step of the cascade process, the optimum deoxygenation degree, as well as high efficiency, in terms both of matter and energy, minimizing at the same time the possible environmental impacts. The project will involve experiments at laboratory, bench and pilot plant scales, as well as a viability study of its possible commercial application. Thereby, the integrated process will be assessed according to technical, economic, social, safety, toxicological and environmental criteria. The consortium will be formed by 17 partners, including 4 research institutions, 6 universities, 5 large industries and 2 SME.

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.
