Selective flotation of ilmenite from olivine using the ...

10/12/2016  The minimum flotation recovery of olivine reached 2.46% when the AWG dosage was 2.5 × 10 − 4 M. The maximum recovery D-value between ilmenite and olivine reached 72.86% at an AWG concentration of 1.5 × 10 − 4 M. Thus, an AWG concentration of 1.5 × 10 − 4 M is used in all microflotation experiments. Download : Download full-size image

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.

Titanium Ore Processing and Beneficiation

09/05/2016  An ore of magnetite and ilmenite may, however, employ wet magnetic separation to remove magnetite, and all flotation for recovery of the ilmenite in a high grade product. In this case all the gravity circuit including the jigs and tables can be eliminated. This scheme is also applicable on a rutile ore with little or no ilmenite.
