In order to produce CeO 2 (99.99%), Pr 6 O 11 (99%), and Nd 2 O 3 (99.9%), the flow rate of the third outlet should be accurately controlled. The acid and NH 3 consumptions are lower than that of flow sheet D although three-outlet technology is used in these two flow sheets but at different steps (Fig. 4.27).
