4 RESEARCH FIELDS From 2004: National R&D Institute for Nonferrous and Rare Metals RESEARCH 100 persons MICROPRODUCTION / TECHNOLOGICAL TRANSFER 10 persons Research fields: from extractive metallurgy to extractive metallurgy & materials Depart 1: ECO-TECHNOLOGIES AND ENVIRONMENT PROTECTION Depart 2: NEW MATERIALS AND TECHNOLOGIES Depart 3: NANOSTRUCTURED MATERIALS

5 1. Mining processes intensification for increasing productivity and decreasing of specific energy consumption. Microwave using in breaking-grinding-flotation of copper ores; Increasing of ore flotation efficiency by intensification of aeration process (new equipment, new technique); Advanced separation of Mo from copper ore, with obtaining of Mo concentrate; Experiments in continuouse flowsheet for processing of complex Cu, Zn, Pb concentrate, Cu-Ni, Ni by promoting our patent for oxidizing with air of nonferrous metals sulphides at small or medium temperature and pressure; Reconsideration and up-date the technologies for obtaining Li, Ti, Zr, REE starting from technologies already known and tested by IMNR.

6 2. Identification and valorisation of new sources for nonferrous metals, (including critical metals), platinum metals, rare metals. Highlighting mining potential for: Complex ores (Cu, Pb, Zn, Au, Ag); Alluvial sands close to Black Sea for Zr, Ti, REE; Sterile mining dump with Te, V, Ga, Au, REE; Ores with platinum content; Spodumen (Li).

7 3. Recycling of wastes and secondary materials with content of nonferrous, critical and rare metals. Recording and characterisation of secondary resources; Processing of mining drainage waste waters and waste waters from metallurgy, with recovery of main metals, using innovative technologies: Cold plasma/electromagnetic fields: synergic efect of both used in the same time; Radiant technology generated by equipments with EB (electron beam); Intensive aeration techniques/oxidation/reduction. Recovery of Ti, Zr and REE by electrolysis in moltem salts from impure ores and wastes; Recovery of Al, Cu, Zn, Pb from slags and volatile dusts;

8 3. Recycling of wastes and secondary materials with content of nonferrous, critical and rare metals. (cont) Recovery of Ga, REE, Ti, Al, Fe from red mud and of Ga (99,999%) directly from bauxite processing; Red mud using in cement industry; Ion exchange coagulants for organic substances, obtain from red mud; Purification and valorisation of silicium from raw materials (secondary) with obtaining of big and pure silicum cristalls for solar panels; Using of metallurgical slags for soil amendaments and significant increasing of productivity.

9 4. New materials. Nanomaterials. Substitution of materials with critical metals content. New high entropy alloys (HEA) with superior mechanical characteristics and corrosion resistance for applications in severe conditions; New solar cells based on non-critical semiconductor materials; Development of materials as thin films and bulk components obtained by soft chemical solutions which can perform in severe operating environments for higher efficiency in manufacturing, energy and transport; Thermodynamic modelling of novel nanostructured oxide systems for energy harvesting (piezoelectric, solid oxide fuel cells, magnetic) based on thin films obtained by hydrothermal-electrochemical and vacuum thermal evaporation system with reducing or replacing rare earth doping elements.

10 4. New materials. Nanomaterials. Substitution of materials with critical metals content. (cont) Ti alloys and powder; Al-Li alloys and other Li alloys; Zr alloys and powder; Cu-Mo-Zr-Y composite (which replace Ag for contacts); Ti implants coated with TiO 2, ZrO 2.

11 5. Techniques and technologies with innovative footprint in applications. Coatings with metals, oxides, carbides by using an EB furnace with 5 guns and obtaining of composite materials using the same technique; Metaloterm reduction and vaccum distillation for refractory metals with high affinity for oxigen (Zr, Ti); Ores and concentrates chlorination in fluidized bed and fix bed; Microwave using for neutralization of medical wastes, drying and smelting of materials, creation of defects/cracks in rocks; Electrolysis in molten salts. 6. Simullation and mathematic modelling of innovative techniques.
