RARE EARTHS: Company recovers rare earths from

Based on our extraction capabilities, we could extract 75 grams of total rare earths out of every 1,000 liters of phosphoric acid from a phosphate mine. This equates to one Florida phosphate mine being able to produce 230 tonnes of total rare earths per year which would supply an estimated 25% of the annual U.S. military needs.”

Scientists Just Found a Way to Extract Rare-Earth

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.
