Ongoing activities

The project was initiated in August 2012. Currently we are working on the following issues:

 

Sources and extraction of rare earth elements

- Minerals processing solutions with reduced environmental impact

Read about our previous work in this area:

- Rare earth element extraction from hard disk drive magnets.

- Examining and testing use of magnetic waste fraction (arfvedsonite) for production of bricks and mortar.

- Verification of the rare earth content at Ilímaussaq (Kringlerne) in Greenland and utilisation of tailings from the deposit.

Electrical machine designs

- Benchmarking recycled magnets in commercial motors

Read about our previous work in this area:

- Permanent magnet generator for wearable energy harvester

- Coating integrity and magnetic performance of reused magnets

- Development of a recycable magnet design for electric motors and generators

- IP magnet recycling

- Design of electrical machines for easy recycling of critical materials, i.e. copper and permanent magnets. The influence of these construction methods are investigated to clarify how the machine performance is affected and hence which penalties may be incurred.
