Highlights
Magnets used in electric vehicles, wind turbines and defence drive rare earths demand.
Processing remains heavily concentrated in China, raising supply security concerns.
Australia is one of the few major producers outside China and is building separation capacity.
Rare earths highlight the challenge of building diverse supply chains for critical commodities. These elements are essential for the powerful magnets used in electric vehicles, wind turbines, electronics and defence equipment. With processing heavily concentrated in China, governments and manufacturers are looking for alternatives, and Australia is one of the few countries with established production outside China.
Magnets Drive Demand
Permanent magnets made from rare earths such as neodymium and praseodymium are central to electric motors and generators. As electrification grows, demand for these materials is expected to rise.
Advanced manufacturing and defence uses add to strategic interest.
Processing Concentration
Mining is only the first step. Rare earths must be separated and refined, and most of that capacity sits in China. Export controls on certain rare earth materials and technologies have sharpened concern about supply security.
Australia’s Growing Role
Australia produces rare earths in Western Australia and is expanding separation and refining capacity. Several projects aim to deliver separated oxides, which are more valuable than mixed concentrate.
Building a Supply Chain
Separation Facilities
Separation plants are complex and costly to build, and they need specialised expertise to run reliably.
Partnerships
Agreements with allied nations and customers aim to secure customers and funding for new capacity.
Policy Considerations
Critical minerals strategies, government financing and trade partnerships are central to the sector’s growth.
What Comes Next for Rare Earths
Watch for new separation capacity coming online, offtake agreements, changes to export controls and government funding announcements. Progress on processing will be the key test.
Rare earths have become a strategic priority, and Australia is well placed to benefit if it can build reliable processing at a competitive cost.
