TOKYO -- The prices of rare-earth metals have tumbled from their June highs after China, a key refiner, resumed the import of ores from Myanmar in September but supply concerns continue to plague the market.
In mid-November, neodymium, an ingredient of permanent magnets used in electric vehicle motors, was traded at around $54 per kilogram, while dysprosium, which is added to improve permanent magnets' heat resistance, was traded at around $230 per kilogram. Both values were 20% lower than their recent highs in June, and at their lowest points since April.
