Lynas Rare Earths has presented plans to build a rare earth oxide separation plant in Brazil's Minas Gerais state, Mines and Energy Minister Alexandre Silveira told MINING.COM. State development bank BNDES is evaluating possible financing, people familiar with the talks said.
At a glance
- The plant would be near Lynas's planned Caldeira project, acquired through its $672 million purchase of Meteoric Resources.
- Silveira said it could be one of the largest industrial rare earth plants outside China.
- Lynas has publicly called Brazilian processing a possible future investment, not a firm commitment.
Background
Separation turns mixed rare earth concentrate into individual oxides such as neodymium and praseodymium, the materials used in permanent magnets. China dominates this step. Lynas is the largest commercial producer of separated rare earths outside China, with operations in Australia and Malaysia.
What happened
Lynas has presented plans for a rare earth oxide separation plant in the Poços de Caldas region of Minas Gerais. Mines and Energy Minister Alexandre Silveira disclosed the plan in written comments to MINING.COM, published on October 12. The plant could be "a milestone for Brazil to advance through different stages of the value chain", he said.
BNDES, Brazil's state development bank, is evaluating possible financing and is expected to visit Lynas's Australian operations before the end of 2026, people familiar with the discussions said. The financing structure and investment decision are not settled, and Lynas did not respond to MINING.COM's questions.
The Caldeira link
The proposal is part of Lynas's expansion into Brazil through its $672 million acquisition of Meteoric Resources, whose Caldeira project holds one of the largest known ionic-clay rare earth deposits outside China. Officials also see the region as a possible processing hub for other nearby clay deposits.
"We could have on Brazilian soil one of the largest industrial rare earth plants outside China," Silveira said.
A test for Brazil's new policy
Lynas has been more cautious publicly, describing Brazilian processing as a possible future investment rather than a firm commitment. The Meteoric deal is expected to be one of the first reviewed by Brazil's new National Council for the Industrialization of Critical and Strategic Minerals, created to encourage processing at home.
Our read
Outlook: neutral. The plant is a proposal with no investment decision, so it does not affect rare earth supply today.
What to watch
- Brazilian regulatory clearance of Lynas's purchase of Meteoric.
- BNDES's technical visit to Lynas's Australian operations.
- Any formal investment decision on the separation plant.

Detailed analysis
Timeline
- 2026-10-12: Brazil's mines minister says Lynas has presented plans for a separation plant in Minas Gerais.
- 2026-12: BNDES is expected to visit Lynas's Australian operations by year-end.
Supply Drivers
A Brazilian separation plant would add rare earth processing capacity outside China.
Government Policies
Brazil's new critical minerals policy encourages domestic processing, and BNDES may help finance the plant.
What could lift prices
- Brazil's government appears supportive of domestic processing.
- The plant could serve several clay deposits in the region.
What could weigh on prices
- Lynas has not committed to the plant.
- Regulatory approval of the Meteoric deal is still needed.
Country impact
| Country | Impact | Reason |
|---|---|---|
| Brazil | High | It could gain one of the largest rare earth plants outside China. |
| Australia | Low | Lynas is an Australian company expanding abroad. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Critical Minerals | Positive | More rare earth separation capacity outside China is planned. |
Who gains, who loses
- Brazil's rare earth developers: A local separation plant could process their material.
Other ways this could play out
- If BNDES financing and approvals come through, Lynas could commit to the plant.
- If not, Caldeira material could be sent through Lynas's existing international processing network.
Price risks
- Rare earth prices are heavily influenced by Chinese supply and export policy.
- Financing and regulatory approvals are not yet settled.
