    2019-1-1 · The effect of pH on the flotation behavior of scheelite and calcite was shown in Fig. 5. The results show that carboxymethyl chitosan has strong depression effect on calcite and the depression effect decreased with the increase of pH. For scheelite, the depression effect of carboxymethyl chitosan is weak.
