Abstract. The separation of rutile from apatite by flotation and the mechanism of depressing the apatite of sodium hexametaphosphate were studied. The results showed that rutile and apatite could be separated by using alkyl-mino-bismethylene phosphoric acid and sodium hexametaphosphate as a collector and a regulator, …
In this work, a new flotation strategy was proposed for the flotation of rutile. In this strategy, rutile was activated by Pb(NO3)2 and then floated with amyl xanthate (AX) as a collector at pH 8. Pb(OH)+ was the dominant lead species in the solution at pH 8 and is believed to be the major species reacting with the rutile surface. Time-of-flight secondary …

Titanium Ore Processing and Beneficiation. To develop a flowsheet for separation of high grade titanium-rutile from ilmenite, that will meet market requirements. Rutile has a SG of 4.2, hardness 6.0 to 6.5 and is non-magnetic; while ilmenite has a SG of 4.5 to 5.0, hardness of 5.0 to 6.0, and is weakly magnetic.
During the flotation experiments, the process was conducted using dodecylamine polyxyethylene ether (AC1203) as collector (Fig. 2), sodium hydroxide (NaOH) and hydrochloric acid (HCl) as the pH regulators.In addition, AlCl 3 and FeCl 3 which are used as ion additives, were purchased from Sinopharm Chemical Reagent …
The flotation tests indicated that rutile fines could be flocculated by SPA, and pH, shear force (stirring speed) and stirring time played significant roles in flocculation. The isoelectric point (IEP) and zeta-potential in whole range all moved to negative values as SPA was added according to the results from zeta-potential measurement.
Metal ions play an important role in rutile flotation, which can be divided into activation and inhibition. The activation ions include Pb 2+, Bi 3+ and Cu 2+, and the inhibition ions include Al 3+ and Fe 3+ . Their mechanism of action is obviously different. In this paper, the commonly used flotation collectors of rutile in recent years are …
The flotation rate constantly increased from 1.213 to 1.731, which implies that the introduction of NBs into the flotation system also results in increasing flotation kinetic rates.

1. Introduction. Rutile in alluvial deposits is typically concentrated by a combination of gravity, magnetic and electrostatic separation techniques [1].However, for hard rock rutile ores, the concentration process also includes flotation [2].Sodium oleate and water-soluble petroleum sulfonate are commonly used as collectors in rutile …

The contact angle measurements for rutile and almandine in the absence of any flotation reagents addition are measured at 39.5° for rutile (Xiao et al., 2018a, Xiao et al., 2018b, Xiao et al., 2018c), while that of almandine was at 38.8° indicating that both minerals were naturally hydrophilic (Kowalczuk et al., 2017). Rutile shows a slight ...
