Mar 01, 2019· For example, to produce one ton of rare earth oxide from ionic-adsorbed clays, 2000 tons of tailings and 1000 tons of wastewater containing heavy metals are generated (Packey and Kingsnorth, 2016). Refining one ton of RE oxide can potentially produce 1.4 tons of radioactive waste (Jiabao and Jie, 2009).

Rare earth elements and high-tech products

A typical distribution of rare earths in an average LREE ore is: 50% Ce, 20-25% La, 12-20% Nd and 4-5% Pr. Following extraction, separation processes are used to produce individual REO. This distribution of rare earths in ores generates an imbalance between rare earth supply and demand (see, e.g., Binnemans et al., 2013): in order to obtain one ton
