Pure Scheelite Flotation Performance. To investigate the effects of NaOl concentration on the flotation behavior of scheelite ground by CB and CIB in parallel, pure scheelite flotation experiments were conducted as a function of NaOl concentration, and the results are shown in Figure Figure1 1 a. It can be seen that when the NaOl concentration is lower than × 10 4 mol/L, the ...
