However, if the stirring strength is not enough, the recovery rate may drop by 4 to 5 or more. In addition, the diameter of the impeller and its position in the tank will also affect the flotation index.

  • Novel Approach For Fine Ilmenite Flotation Using

    The flotation recovery of ilmenite in acidic aqueous solutions first increases sharply with the increase of pH, stabilizes above 50 when pH is over 5.0, and continues to increase in a weakly alkaline environment. Floatability of fine titanaugite trends is remarkably similar to fine ilmenite.
