4.3.2.5 Conventional Flowsheet E. In flow sheet E, the three-outlet process is used in the first step, in which, La, Ce mixture (Ce, 80%), Pr concentrate (Pr, 30%), and mixture of Nd and Sm ~ are produced simultaneously. The high concentration of Pr is beneficial for its further purification. This flow sheet makes use of the advantage of the ...
