In the presence of ammonia, uranium is precipitated as ammonium di-uranate (ADU). The ADU slurry (15 wt% U 3 O 8) is then filtered and dried to ADU powder, which is finally calcined to U 3 O 8 at 490 °C. Samples were collected at each stage of the process in order to follow the flow of material originating from the same feed.
