Work packages

WP1: A circular economy context and assessment of health, environmental and economic aspects and legal compliance.

This work package aims to map the potential of the developed CHROMIC technologies and applications in terms of environmental impact, economics and circular economy, health and safe risks and legal compliance.

It will run throughout the whole project. Its tasks include both preliminary context analysis and a continuous evaluation during the project and its technology development. WP1 partners will allow early feedback to other work packages and steering of development activities.

The work package is led by ARCHE (Belgium).


WP2: Efficient mineral processing procedures for enhanced beneficiation of by-product and critical metals.

By-product metals such as chromium, niobium, molybdenum and vanadium are extracted from major metals and are present in composite materials (metal matrixes). There are several ways to separate by-product metals from other materials: WP2 will focus on comminution and beneficiation, that are pre-treatment processes, focused on the crushing, milling and disintegration of metal matrixes. Nowadays, these techniques are expensive: the main goal of WP2 is to develop innovative processes that can assure a tailored physical separation of valuable metals from residue matrix and slag materials. Among the WP2 targets there is also to prepare materials for further processes in WP3.

It will run from the beginning of the project until month 48.

The work package is led by MEAM (Belgium).


WP3: Highly efficient and selective hydrometallurgical extraction technologies for by-product and critical metals.

WP3 will develop highly efficient and selective leaching processes for by-product and critical metals from alkaline streams. Leaching is the dissolution from ore or concentrates after suitable comminution to expose the valuable minerals, by aqueous and chemical attack. To improve leaching means minimize energy and reagent consumption. To do so WP3 will test innovative technologies based on dialectric heating, roasting, ozonation and ultrasound. Among the WP3 targets there is also to prepare materials (leachates) for further recovery processes in WP4.

It will run from the month 7 until month 30.

The work package is led by BFI (Germany).


WP4: Highly selective metal recovery techniques for complex metals mixtures including by-product and critical metals.

In this work package, the leachates obtained in WP3 will be treated further to enable highly selective recovery of valuable and critical elements such as chromium, vanadium and molybdenum which will be present in the solutions obtained in the previous work package. Important researches and method indications will be given to WP4 also from WP1, which will set the targets of recovery processes, the required purity and chemical form (pure metals, salts) of the final product of WP4.

It will run from the month 13 until month 36.

The work package is led by HZDR (Germany).


WP5: Metallurgical system validation.

This work package is based on the outputs of WP2, 3 and 4. The main goal of WP5 is validation: it will define technical boundary conditions for the entire process development and it will validate the new metallurgical systems used for recovery of chromium, molybdenum, vanadium and niobium with an important focus on economic and environmental sustainability. WP5 will also have to test technical readiness level (TRL) of some of the technologies studied in the previous WPs.

It will run from the month 31 until month 48.

The work package is led by ORBIX (Belgium).


WP6: Communication, dissemination and societal trust. 

This work package’s objective is communication, dissemination, storytelling and community involvement. WP6 will define the CHROMIC visual identity, communication toolkit and dissemination plan. Also, WP6 aims to stimulate and assure community involvement through the organization of events and focus groups.

It will run from the month 1 until month 48.

The work package is led by formicablu (Italy).


WP7: Project management.

This work package coordinates the project. The main goal is to achieve proposed objectives and deliver high-quality results within the given times and costs. Among its targets are the coordination of partners, review and validate reports and deliverables, organize project meetings, establish the strategy for the entire CHROMIC project and promote gender equity in the consortium.

It will run from the month 1 until month 48.

The work package is led by VITO (Belgium).


WP8: Ethical requirements.

This final work package manages the processing of personal data and intellectual contents developed in activities of WP7. This work package wants also to coordinate all the ethical and legal aspects connected with experiments and safety procedures for workers and researchers in all the consortium’s laboratories.

It will run from the month 1 until month 48.

The work package is led by VITO (Belgium).
