4. Conclusions
- The use of DBP in reverse flotation of collophane significantly improved the collecting potency and selectivity of CTAB for quartz at all pH’ and CTAB concentrations examined.
- Concentrate P2O5 grade and recovery obtained in the presence of DBP was substantially higher than that generated in the absence of DBP at the same CTAB concentration.
- The addition of DBP reduced the solution surface tension and the bubble size and improved the collision efficiency between the bubbles and the quartz particles.
- DBP improved the aggregation behavior of the coarse and fine quartz particles due to the strong hydrophobic interaction between the hydrophobic quartz particles and DBP droplets with stronger affinity for the quartz surface than for kerosene droplets.
- The introduction of DBP at a suitable dosage promoted defoaming and reduced the hydraulic entrainment of fine collophane particles.
