Integrated Innovative Pilot System For Critical Raw Materials Recovery From Mines Wastes In A Circular Economy Context

A 42-month EU funded project driven by 19 partners from 9 EU countries, 1 non-EU country and 2 international
partners, aiming to develop and demonstrate an innovative pilot system for the clean and sustainable
production of non-energy, non-agricultural raw materials from Mine Waste (MW) resources has been

by the EU, RAWMINA project officially started in May 2021. The project addresses major challenges for the nternational mining industry, and will deliver significant impact across the European Economy, Environment and Social Wellbeing. 

Funded by the Horizon 2020 program, under the Grant Agreement nº958252, RAWMINA benefits from an overall budget of about 10.8M€ with an allocated European funding of about 9M€ (see Fig. 1) to be expend in 42months. European competitiveness is strongly supported with a 26.4% and 30.3% of total budget for innovative SMEs and large industries, respectively. The consortium covers 9 countries (European: Czech Republic, Finland, France, Germany, Greece, Ireland, Italy, Spain; International; Chile, UK) and includes 5 RTOs, 3 universities, 4 large enterprises and 7 SMEs. Coordinated by LEITAT, and involving a prominent industrial partner from Chile, where the world’s largest copper ore deposits exist, the consortium will also everage the knowledge and support of the Advisory Board members, including expertise from the mining sector in South Africa, Portugal and Turkey.



How RAWMINA will solve it

RAWMINA aims to develop and to demonstrate the RAWMINA pilot system: an industrially scalable and flexible innovative pilot in continuous operation for MW valorisation, achieving 95% recovery rate and 95% selectivity for CRMs (Co, Sb, Ge, W), and 80-90% recovery rate and 95% selectivity for Gold (Au), Silver (Ag) and Iron (Fe) based high-value products, whilst reutilising 90% of water. The RAWMINA pilot system will treat up to 100-150 kg MW/day on an industrial demonstration (TRL7, 12 months operation) and includes an efficient, circular and robust process control by an end-to-end Intelligent Management System.

To achieve these aims, RAWMINA activities include MW conditioning and characterization, optimization and upscaling of innovative technologies, such as continuous bioleaching, iron removal with magnetic separation & by-products recovery, selective recovery of Co, Sb, Ge and W through a combination of Nanofibrous Composite Materials, Thermo-Desorption Process and Electro Winning followed by other metals recovery by Electro Coagulation, process simulation, integration, and pilot design, System engineering & Demonstration. The sustainability and social impact of these technologies will be checked and finally the exploitability of the project will be analysed with a Circular Business Plan. The project will create a unique community, named “CRM Recovery Helix” to maximise clustering and dissemination to all the relevant stakeholders (researchers, industries, investors, municipalities, policy makers, NGOs, Society)

An interdisciplinary, vibrant, industry led consortium, formed by 19 partners, with recognized expertise, experience, skills, resources, infrastructure and position in the fields of mining industry, circular economy, renewable energy, material sciences, and business development, is prepared to achieve these goals. Finally, RAWMINA will contribute to reduce production costs and environmental impacts, contributing to the objectives of the European Innovation Partnership on CRMs.
