Precision Periodic extracts of 80% total REEs in five ...
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."

Bioaccessibility of lead from contaminated soil using ...
Phosphate treatments are used to immobilize lead in soil by forming pyromorphite. Soil from Bonne Terre, Mo was collected to study whether such treatment decreases the bioaccessibility of lead. The soil was treated using soil wt% of phosphate. Treatments were: none, phosphoric acid, triple super phosphate, and organic bone meal.

Otherwise, various ammonium phosphate fertilizers can be produced by reacting the phosphoric acid with ammonia. The uranium is normally recovered from the phosphoric acid (H 3 PO 4 – bearing about 28% P 2 O 5) by some form of solvent extraction (SX). Kamorphos is developing a simpler version of this.

examined effectiveness of phosphoric acid (PA) and/or phosphate rock (PR) in immobilizing Pb, Cu, and Zn in two contaminated soils. The effectiveness was evaluated using water extraction, plant uptake, and a simple bioaccessibility extraction test (SBET) mimicking metal uptake in the acidic environment of human stomach.
