Milling This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining. The ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. The uranium is then separated from the chemical solution, solidified, dried and packaged.

We present a method to measure carbonate content of apatite that uses infrared spectroscopy. The method was calibrated against the amount of CO 2 released by reaction of apatite with phosphoric acid and may be used to study apatite with CO 2 content below 1 wt. We have applied the method to apatite from carbonatite ≈0.3–0.4 wt CO 2 and metasomatic ≈0.61.0 wt CO 2 and alkaline ...
