The individual rare earth complexes R3 + form rectangular bands with a minimum overlap of adjacent bands. The given rare earth solution is collected and the R3 + ion is precipitated from the solution with oxalic acid. The rare earth oxalate is converted to the oxide by heating in air to 800-1.000 ° C (1.472-1.832 ° F). Solvent extraction

In this time of increased focus on renewable energy technologies, rare earth elements (REEs) are of critical importance. For example, neodymium (Nd) is a REE used in the generator and motor magnets of wind turbines and electric vehicles. Reliance on REE imports puts the U.S. at high risk for supply disruption.

Rare earth is a general term for 17 elements, including 15 elements (lanthanoid*1) with atomic numbers 57 to 71 in the Periodic Table plus scandium (Sc) with 21 and yttrium (Y) with 39. Rare earth was discovered in Sweden in 1794 and was called "rare" (earth) because it was considered to be an extremely rare substance at that time.
