Production of rare earth oxides from raw ore in fluidized bed
2020525 The objective of this thermochemical processing is to produce a high-grade mixture of rare earth elements (e.g. above 90%), for example, in the form of either rare earth oxides or rare earth chlorides (depending on the process economy and market needs) upfront of their separation in individual forms. Baking process, for instance, with sulfuric
Changes in Microfine Particle Migration of Ionic Rare Earth
2023220 The hydration mechanism between the leaching agent and ore surface during the leaching process of ionic rare earth ore is complicated, and the inter-particle bridge cementation is prone to fracture due to the existence of multiple forces and dispersion during ion adsorption and exchange, resulting in migration and rearrangement of

201891 After extension of the leaching process by a second stage, the leaching efficiency may reach up to 96.19%, which is slightly higher than that obtained by (NH 4) 2 SO 4. Leaching varies from element to element, with Ce presenting the lowest leaching efficiency, and the partition in leaching solution is in agreement with that in raw ore other
Who is the core? Reveal the heterogeneity of global rare earth
202351 The U.S. occupies an important position in rare earth production and processing and is a major exporter and consumer. Although China's export scale is fairly high, it is located in the semi-core circle because of chaotic production. As the largest rare earth ore market, Europe dominates the flow of rare earth ore.
Global rare earth elements projects: New developments
202361 Rare earth elements resources production, consumption, and processing activities are significantly uneven around the world. Global production of REOs (210,000 of 300,000 tons in 2022) is dominated by China (70%), followed by U.S. (14%), and Australia (4%) (Fig. 1; USGS, 2023).China also has a dominant share of global REOs processing
