2.2.1 Occurrence. Rare earth minerals occur as fluorites, oxides, tantalates, carbonates, phosphates, sulfates, borates, silicates, etc. (Qi 2018).List of different rare earth minerals are presented in Table 2.3.The average concentration of REEs in the earth's crust is found to be 150–220 ppm, which is much higher than the concentration of other …
The individual rare-earth R 3+ complexes form rectangular bands with a minimum overlap of adjacent bands. The given rare-earth solution is collected, and the R 3+ ion is precipitated out of solution using oxalic acid. The rare-earth oxalate is converted to the oxide by heating it in air at 800–1,000 °C (1,472–1,832 °F). Solvent extraction
