The effect of aluminum ions on the flotation separation of …
Barite is easily ground to slime fraction, which may affect the fluorite flotation. The role of barite particle size in the fluorite flotation was studied in this work. Single mineral flotation showed that gelatinized starch (GS) selectively depressed the barite flotation with different size fractions while it had little effect on fluorite ...
