Work packages

The CRM Västerbotten project covers the entire chain from exploration to metal extraction.
The three work packages build on each other and together create a whole where knowledge, technology and methods are developed step by step.

WP1 coordinates the project, follows up results and ensures that the research is widely communicated.
WP2 develops new technologies for exploration, geochemical tools and sustainable mining.
WP3 takes up the value chain and focuses on how metals can be extracted efficiently and in an environmentally friendly way through geometallurgy and advanced mineral engineering.

Together, the work packages form a coherent research chain that strengthens Europe's ability to secure access to critical metals for the green transition.

WP1 - Coordination and dissemination of information

Task Leaders: Hans Åhlin, Thomas Aiglsperger
Description: Ensures project management, reporting, meetings and communication - both internal and external. Includes dissemination of results via workshops and networks.

The first work package ensures that the CRM Västerbotten project is run efficiently and transparently throughout the project period. It coordinates all parts of the project - from research activities to communication and results reporting.

WP1 is led by Hans Åhlin and Thomas Aiglsperger at Luleå University of Technology and is responsible for ensuring that the work packages follow set goals, schedules and milestones. The work package organizes project meetings, steering group meetings and external workshops where industry and other stakeholders can contribute with views and ideas.

An important part is also to make the results available, both through scientific publications and popular science communication. WP1 also serves as the hub for contact with the project's external advisory group, which consists of representatives from industry and authorities in the region.

WP2 - Exploration and mining

Task leaders: Thorkild Maack Rasmussen
Description: Research on new technologies for exploration, geochemical tools and sustainable small-scale mining. Focus on the Nickel line in Västerbotten.

Sub-projects:

• Development of new software for interpretation of geophysical data.
• Database for exploration according to the FAIR principle.
• Strategies for integrated and carbon-neutral mining.

The second work package focuses on developing new methods and tools to identify and extract critical metals in Västerbotten in a sustainable way. The work is led by Thorkild Maack Rasmussen at Luleå University of Technology and includes both research and practical case studies in the area around the so-called Nickel line, south of the Skellefte field.

Content and subtasks

2.1 Exploration
Development of new software and methodology for interpretation of geophysical and geochemical data. The aim is to streamline exploration and reduce the number of necessary drillings - saving both resources and environmental impact.

2.2 Integrated and sustainable mining
Research on how to integrate social, environmental and technical factors at the early stages of planning small and medium-sized mines. Models for selective mining and smart resource use are being developed.

2.3 Geochemical tools
Development of new analytical methods for the detection of metals from primary, secondary and recycled sources. Advanced isotope and multi-element analyses are used to understand metal flows and circularity.

2.4 Carbon neutral mining
Investigations into how electrification, battery-powered machines and energy-efficient ventilation can reduce emissions and improve the working environment in small-scale mining.

Results and outcomes

WP2 contributes with new technology and computer models that strengthen Sweden's and Europe's ability to secure access to critical metals. The work also provides a basis for industrial decisions on future exploration and sustainable mining in northern Sweden.

WP3 - Geometallurgy and mineral engineering

Task Leader: Jan Rosenkranz
Description: Develops methods for efficient extraction of metals from small deposits. Focuses on resource efficiency, flexibility and environmental considerations.
Subtasks:

• Geological and mineralogical studies
• Geometallurgical models
• Design of flexible processes
• Development of hydrometallurgical methods for PGE

The third work package is about developing knowledge and technology to improve the whole chain from ore to metal - with a special focus on small-scale deposits. WP3 is led by Jan Rosenkranz at Luleå University of Technology and combines expertise in ore geology, mineral engineering and process metallurgy.

Content and subtasks

3.1 Geological and mineralogical studies
Mapping of mineralization of nickel, copper and platinum group metals along the Nickel Line. The aim is to understand how the mineral composition affects the recovery.

3.2 Geometallurgical studies
Development of an integrated framework linking mine planning, mineral engineering, metallurgy and economics. The model allows optimization of processes for small-scale deposits.

3.3 Design of mineral processes
Design of flexible beneficiation processes that can be adapted to different types of ore, product requirements and throughput - either in small, portable plants or larger plants serving several mines.

3.4 Metallurgical extraction of PGE
Development of hydrometallurgical methods for the efficient and environmentally friendly extraction of platinum, palladium and rhodium. The aim is to maximize metal recovery and minimize waste.

Outcome

WP3 will deliver a holistic model for sustainable metal production in Västerbotten, where geology, technology and environmental considerations are woven together. The results will provide industry with new tools to develop small-scale deposits in an economically and ecologically sustainable way.
