Pyrometallurgy and electrometallurgy of rare earths
The minimum rare earth oxide (REO) grades of traditional rare earth minerals (bastnaesite, monazite, Xenotime) and non-traditional minerals such as ion-adsorbed for industrial mining are about 1.5% – 2.0% and 0.06% – 0.15%, respectively. This suggests, rare earth mineral deposit with concentrations less than these cannot be …
