Scientists Just Found A Way To Extract Rare

The good news is there's a lot of it – about 100,000 tons of these REEs end up in phosphate rock waste every year. Even though the elements only make up about 0.1 percent of phosphate rock, the amount of waste produced means the annual production of rare earth oxides could be almost doubled, in theory.
