Rare Earth Production Outside China 'Major Milestone'

An Australian firm's production of a heavy rare earth, a first outside of China, is a "major milestone" in diversifying a critical supply chain dominated by Beijing, experts say.
But the announcement by Lynas Rare Earths also illustrates how much more needs to be done to broaden the supply of elements critical for electric vehicles and renewable technology.
Rare earth elements (REE) are 17 metals that are used in a wide variety of everyday and high-tech products, from light bulbs to guided missiles.
Among the most sought-after are neodymium and dysprosium, used to make super-strong magnets that power electric car batteries and ocean wind turbines.
Despite their name, rare earths are relatively abundant in the Earth's crust. Their moniker is a nod to how unusual it is to find them in a pure form.
Heavy rare earths, a subset of overall REE, have higher atomic weights, are generally less abundant and often more valuable.
China dominates all elements of the rare earths supply chain, accounting for more than 60 percent of mining production and 92 percent of global refined output, according to the International Energy Agency.
Lynas said it produced dysprosium oxide at its Malaysia facility, making it the only commercial producer of separated heavy rare earths outside of China.
It hopes to refine a second heavy rare earth -- terbium -- at the same facility next month. It too can be used in permanent magnets, as well as some light bulbs.
It "is a major milestone," said Neha Mukherjee, senior analyst on raw materials at Benchmark Mineral Intelligence.
The announcement comes with China's REE supply caught up in its trade war with Washington.
It is unclear whether a 90-day truce means Chinese export controls on some rare earths will be lifted, and experts say a backlog in permit approvals will snarl trade regardless.
"Given this context, the Lynas development marks a real and timely shift, though it doesn't eliminate the need for broader, global diversification efforts," said Mukherjee.
Lynas did not say how much dysprosium it refined, and rare earths expert Jon Hykawy warned the firm faces constraints.
"The ore mined by Lynas contains relatively little of the heavy rare earths, so their produced tonnages can't be that large," said Hykawy, president of Stormcrow Capital.
"Lynas can make terbium and dysprosium, but not enough, and more is needed."
The mines most suited for extracting dysprosium are in south China, but deposits are known in Africa, South America and elsewhere.
"Even with Lynas' production, China will still be in a position of dominance," added Gavin Wendt, founding director and senior resource analyst at MineLife.
"However, it is a start, and it is crucial that other possible projects in the USA, Canada, Brazil, Europe and Asia, also prove technically viable and can be approved, so that the supply balance can really begin to shift."
China's domination of the sector is partly the result of long-standing industrial policy. Just a handful of facilities refining light rare earths operate elsewhere, including in Estonia.
It also reflects a tolerance for "in-situ mining", an extraction technique that is cheap but polluting, and difficult to replicate in countries with higher environmental standards.
For them, "production is more expensive, so they need prices to increase to make any seriously interesting profits," said Hykawy.
That is a major obstacle for now.
"Prices have not supported new project development for over a year," said Mukherjee.
"Most non-Chinese projects would struggle to break even at current price levels."
There are also technical challenges, as processing rare earths requires highly specialised and efficient techniques, and can produce difficult-to-manage waste.
Lynas has commissioned more processing capacity at its Malaysia plant, designed to produce up to 1,500 tonnes of heavy rare earths.
If that focused on dysprosium and terbium, it could capture a third of global production, said Mukherjee.
The firm is building a processing facility in Texas, though cost increases have cast doubt on the project, and Lynas wants the US government to pitch in more funds.
US firm MP Materials has also completed pilot testing for heavy rare earth separation and plans to boost production this year.
Canada's Aclara Resources is also developing a rare earths separation plant in the United States.
And Chinese export uncertainty could mean prices start to rise, boosting balance sheets and the capacity of small players to expand.
"The Lynas announcement shows progress is possible," said Mukherjee.
"It sends a strong signal that with the right mix of technical readiness, strategic demand, and geopolitical urgency, breakthroughs can happen."
