Rare earths are found in natural deposits with varying abundance, mineralogy, and textures. The proven global rare earth oxide (REO) reserves are estimated at about 110 million tons (Wang et al., 2015), with about 43% of the global reserves located in China. Namibia has the second-largest reserves worldwide, with 20 million tons.
