Rare earths miner Arafura Resources will test samples of concentrates from its Australian mine as potential feedstock for a refinery in Colorado-owned by USA Rare Earth, it said in a statement on Wednesday.
Arafura plans to send samples of a refined liquor comprising middle and heavy rare earths, produced from its ores processed at an Australian government plant, to the USA Rare Earths’ pilot plant in Colorado to separate into individual heavy rare earths, the company said in a stock exchange statement.
