Abstract

Abstract

Magnetic separation plus flotation has gradually become the best process for comprehensive recovery of ilmenite. Flotation recovery is faced with the characteristics of large specific ore, coarse particle size, high slurry concentration (ca. 65%), and high mass pull. According to the existing flotation process, the flotation dynamics test and analysis of the titanium flotation equipment were carried out. The air dispersion test shows that the air dispersion of each flotation equipment is low, and the air is unevenly dispersed on the cross section of the tank. At the same time, the air dispersion of the slurry suction flotation cell is obviously lower than that of the direct flow tank, and the effect of air dispersion is not good enough. The bubble loading rate test shows that the coarse-grained minerals have a high probability of falling off during the upward transportation process, and the recovery effect is poor. The slurry suspension test shows that there is obvious slurry stratification phenomenon in all flotation equipment, that is, the slurry concentration is not much different below 1100 mm from the overflow weir. As the depth from the overflow weir decreased, the concentration decreased significantly. The slurry concentration in the area near the overflow weir is obviously lower than that in the area of the impeller. The uneven distribution of gas holdup in the flotation equipment indicates that there is no regularity in the operation of the flotation equipment, and the probability of collision and adhesion between mineral particles and air bubbles cannot be guaranteed.
