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.

protection
- Development of test setup for combined testing
- Development of thin, sol-gel based protective coating for
neo-magnets
