Selective extraction of uranium from uranium–beryllium

2019-8-3  Sulfuric acid is very efficient in selective extraction of U from low grade U–Be ore. Experimental results indicate that leaching process carried out by 0.2 M sulfuric acid at 348.5 K for 50 min with the solid–liquid ratio of 0.25 g/mL helps to obtain the highest leaching efficiency of uranium (97.4%).

Uranium in Namibia - World Nuclear Association

There is good potential to significantly upgrade the uranium plant feed grades by sizing and gravity separation, achieving beneficiation from 0.01% to 0.55% U 3 O 8, and increasing the leach feed grade accordingly. The uranium occurs as carnotite of a particular particle size, significantly denser than the host gangue, mainly calcite.
