Utah rare earth expansion The White Mesa Mill already produces up to 1,000 metric tons of separated neodymium-praseodymium (NdPr) oxide each year. Energy Fuels has now started construction on an expansion that will add commercial production of heavy rare earth oxides, including terbium and dysprosium, by the end of 2027. Once complete, the expansion will give the Utah facility annual capacity to produce approximately 20 metric tons of terbium, 120 metric tons of dysprosium, 140 metric tons of samarium, 20 metric tons of europium and 140 metric tons of gadolinium oxides. After processing at White Mesa, the rare earth oxides will move to Australian Strategic Materials’ facilities in South Korea for conversion into rare earth metals and alloys. The company also plans to install a processing circuit for mixed rare earth carbonates, allowing the mill to process a broader range of feedstocks while producing uranium and rare earth oxides simultaneously.
