:: Precision Periodic extracts of 80% total REEs in five minutes from phosphate mine waste

 

Precision Periodic has announced the successful results of projects for Florida Industrial and Phosphate Research Institute capturing, extracting and separating Rare Earth Elements (REE) out of both phosphoric acid and the resulting waste using the reusable Thor nano-filtration system. The filter captured 40-60% of the rare earth elements and radioactive elements in a five minute single pass-through from wet process phosphoric acid and 80% of the rare earth elements in a five minute single pass-through from sulphuric acid leached waste.

“The successful test projects proved that the Thor nano-filtration technology could be a game-changer for US production of its own rare earth elements supply,” says Brian J Andrew, CEO of Precision Periodic. He continues, “The phosphoric acid contains 150 ppm of total rare earths. Based on our extraction capabilities, we could extract 75 grams of total rare earths out of every 1,000 litres of phosphoric acid from a phosphate mine. This equates to one Florida phosphate mine being able to produce 230 metric tons of total rare earths per year which would supply an estimated 25% of the annual US Military needs.”
