The scheme was applied to closed-circuit flotation (one-stage rougher flotation, two-stage scavenger flotation and two-stage cleaner flotation), produced a concentrate of 92% TiO 2 with the recovery of 70%. It is shown that the new chemical scheme would be a potential one for the effective separation of rutile from eclogite ores.

The Bureau of Mines investigated the potential for recovering rutile and associated valuable heavy minerals from the Central Florida Pebble Phosphate District flotation circuits. Studies were made to determine (1) the type and quantity of valuable heavy minerals present at various points in the flotation circuits and (2) the technical ...

Lead hydroxyl compounds are known as rutile flotation of the traditional activated component, but the optimum pH range for flotation is 2–3 using styryl phosphoric acid (SPA) as collector, without lead hydroxyl compounds in slurry solution. In this study, Bi3+ ions as a novel activator was investigated. The results revealed that the presence of Bi3+ ions increased the surface potential, due ...

excess of 5 million mt, with a potential rutile recovery rate of 300 mt/d. Sullivan and Llewellyn (~) estimated that recovery of rutile from two of the tail­ ings they investigated would amount to about 32 pct of 1980 U.S. imports. A rutile flotation technique for rutile-bearing-Cu mill tailings was developed by Llewellyn and Sullivan (!).

rutile using micro-flotation, zeta potential, and solution chemistry analysis. Compared to the previous studies (Li et al., 2016; Xiao et al., 2017), the effects of lead ions and aluminium ions on electro kinetic500 and flotation behaviour of rutile are systematically compared. Furthermore, solution species are

The flotability of monazite, zircon and rutile in the presence of sodium oleate, potassium octyl hydroxamate and a commercial hydroxamate was investigated through microflotation tests in a modified Hallimond tube. Zeta potential determinations in the absence/presence of collectors were performed in a microelectrophoretical cell. The microflotation testwork showed that, in general, the ...

Rutile flotation without grinding the plus 200-mesh material is feasible and appears to be the most promising technique for rutile beneficiation. A rutile concentrate grading 34.7 percent TiO2 with recoveries of 69.4 percent of the recoverable TiO2 and 36.8 percent of the total TiO2 was obtained using as-received (not ground) tailings.

Al³⁺ ions were adsorbed on the rutile surface in the form of Al(OH)ₙ³⁻ⁿ (n = 0, 1, 2), which increased the zeta potential and the activating sites for anionic collector adsorption. The addition of EDTA removed the surplus Al³⁺ ions, and prevented the generation of hydrophilic colloidal Al(OH)₃ over the pH range of optimum flotation.
