Australia's Lynas is teaming with Texas-based Blue Line on a heavy rare earths separation plant. But, once the oxide is generated at the separation plants, it may still have to go to China for further processing.
China uses gravity separation and froth flotation. Beneficiation increases the concentration of rare earth minerals from 1–10 per cent in the rock to commonly 50–60 per cent. This process is normally carried out close to the mine. The resultant concentrate can then be transported to a plant for further rare earth oxide separation and ...

2.2 Smelting and manufacturing. In the smelting process, the production amounts for different rare earth elements are significantly different. The amounts of several bulk rare earth elements, such as Nd, La, and Y, are hundreds of times that of other elements, such as Lu, Tm, and Er (Goodenough et al., 2018).Such differences are …
Rare earth elements (REEs) are essential raw materials vital for the advancement of modern high-tech industries. However, their extraction often leads to environmental concerns. The similar chemical properties of REEs contribute to high energy consumption and significant pollution emissions during the separation process. To address these …
Sichuan Mianyang rare earth deposit in China is found to be an alkaline carbonate-type rare earth deposit, which has an average REO grade of 3.7% (Chi et al. 2001).
