Objectives of the commitment
1) To develop a novel biotechnical process for sustainable exploitation of EU metal resources such as laterites, polymetallic deep-sea nodules and weathered sulfide ore deposits.
2) To tailor downstream process for the specific recovery of the metal by-products cobalt (CRM) and scandium together with the main metal nickel. Other metals solubilised during bioprocessing (such as Cu, Zn, V and Mn) will also be targeted.
3) To validate the technology at TRL 5 for laterites in a pilot scale operation, preparing its future industrial application.
4) To increase the competitiveness of EU mining companies and technology providers (including SMEs).
5) To increase EU metal production potential as well as securing metal supply from EU sources and thus lowering supply risks for European industry.
6) To stimulate private engagement, investment and job creation in the European mining sector.
Description of the activities
RUBICON is an industrially-driven and led consortium with two mining companies (providing the case studies) and two technology providers in the field of mining. The consortium is completed by eight R&D institutions with strong experience in applied research and collaboration with industry. Market uptake of the RUBICON technology will be facilitated and organised in an industrially led work package on exploitation. This WP will include potential end-users (two mining companies) and will present the results of the techno-economic feasibility of the RUBICON process to be developed.
The RUBICON project specifically targets nickel-rich oxide ores and residues with the main by-products cobalt (CRM) and scandium as well as copper, manganese, zinc and vanadium. Industrial biomining of sulfide ores is an industrial reality but biomining of oxide ores is yet to be demonstrated in pilot- and full-scale operations.
In several laterite mines the limonitic oxide ores are stockpiled as mine residues (or accumulated as waste), for example at Koniambo in New Caledonia, due to the lack of a suitable processing technology. RUBICON will develop a bio-based environmentally-benign process that will extract the above mentioned metals from these residues without additional mining. However, the RUBICON process will also be suitable for new laterite ores and weathered sulfide ore deposits on land and marine deep-sea nodules and crusts.
Based on previous research experience and clustering with current EU projects related to biomining involving several RUBICON partners (BioMOre, ProMine, BioMinE, Bioshale and SysMetEx), as well as on the experience of two partners in developing the initial laboratory Ferredox reductive bioleaching process for laterites (du Plessis et al. 2011; Johnson et al. 2013; 2015 a and b; Ãancucheo et al. 2014), the RUBICON project will validate and demonstrate the technology at TRL 5 in a pilot scale operation for laterites (Gleeson et al. 2003; Eliopoulos et al. 2012). For deep-sea nodules and weathered sulfide ore deposits, the RUBICON technology will be optimised and validated at TRL 4. To develop a complete process, upstream and downstream processes are incorporated as well as economic and environmental analyses. Technology transfer and public outreach is secured.
WP1 will ensure a smooth project coordination and management. WP2 includes the description and analysis of the ore from the different mineral deposits and the processing products. WP3 will optimise bioleaching in laboratory bioreactor experiments with the various samples and with the help of modelling. WP4 will develop enhanced techniques for the extraction of metals from the leaching liquor (pregnant solution). WP5 analyses and integrates process parameters from WP3 and WP4 for upscaling, including reactor design and operation at the pilot scale developed according to economic and environmental considerations. WP6 will develop the exploitation strategy for the RUBICON process for technology transfer including market analysis and a prefeasibility study. WP6 will develop the exploitation strategy for the RUBICON process for technology transfer including market analysis and a prefeasibility study, and assess future research and technological development potential. WP7 will disseminate project description and results from all WPs to stakeholders, policy makers, industry, scientific community and the public.
Description of the expected impacts
The RUBICON technology based on reductive bioprocessing enables the exploitation of yet unused limonitic laterite ores and stockpiles in existing mines adding substantial value without additional exploration. These materials cannot be economically processed with current technologies. RUBICON technology is scalable, meaning that it should be applicable to ores of modest sizes, and not necessarily just to mega-deposits, like those where HPAL is used.
The RUBICON technology application increases European metal production including CRM to secure metal supply from European sources thus lowering delivery risks for European industry. The increased process efficiency of the RUBICON technology in comparison to existing laterite processing technologies (AHL and PAL/HPAL) is reflected in lower operational costs and a reduced environmental footprint (less energy and acid consumption). This technology can also be used for the exploitation of other oxide primary and secondary materials such as deep-sea nodules, oxidised zones of sulfide ores and mine/industrial waste.
Whereas HPAL technology requires mega-deposits to ensure high throughput rates and long term profitability, the RUBICON technology is based on known equipment and common materials of construction, thus ensuring that the technology is scalable to smaller throughputs. As such, it has the potential to unlock many European laterite deposits that would not be classified as mega-deposits. European mining and downstream processing applications as a result of the applied RUBICON technology would create new jobs and secure existing jobs in Europe. This project will increase collaborative partnerships. The new knowledge generated will be published in international journals, commercially exploited or patented.
