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 …

Very limited information on rutile flotation is available in the literature. Purcell and Sun (1963) studied the flotation of rutile crystals by unsaturated fatty acids (oleic, linoleic and linolenic acids). They found that rutile crystals could be floated in a wide pH range from 2 to 11 when the concentration of oleic acid was 10-3 mole/liter.

The flotation and surface interaction of rutile with nonyl hydroxamic acid were investigated in this work. The results show that the adsorption density and flotation recovery of rutile have similar tendency, especially the maximum recovery and adsorption occur at pH about 7.5. In terms of Fourier transform infrared (FTIR) spectroscopic …

The best flotation pH range was 2–2.7, which was the natural pH of the SPA solution. The flotation recovery of rutile in the absence Al 3+ and EDTA reached a maximum value (around 65.8%) at pH 2.2. The flotation recovery of rutile slightly increased after adding only Al 3+ ions (from 65.8% to 69.7%). In the presence of EDTA and without Al 3 ...

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 …

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 …

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, …

Micro-flotation results indicate that the Pb(II) ions can effectively improve the flotation recovery of rutile while the Al(III) ions significantly inhibit the flotation of rutile.

Due to the weak hydrophobicity of styrene phosphoric acid (SPA), the amount used as a collector for rutile flotation is too large, resulting in high beneficiation costs. In this study, SPA was modified by …

The flotation behavior of rutile in the system with sodium oleate as collector was studied through pure mineral test. When the dosage of sodium oleate is 20 mg/L, and pH value of the pulp is set ...

In this paper, −10 μm rutile and −30 μm garnet particles were selected as samples. The effects of different reagents on the flotation of rutile and garnet single minerals were studied, and ...

The effect of pH on the flotation recovery of rutile is shown in Fig. 3. Rutile shows good flotability at a neutral pH range from 5 to 9, which is in good agreement with the earlier study [4]. In the acidic condition, the recovery increases with the increase of the pH. When pH[8, the Fig. 1 XRD pattern of rutile Fig. 2 Flotation flowchart of ...

Several surfactants were tested as emulsifiers and one was found to have the least adverse effects on the selectivity of the composite collector. By using the composite collector that contained SPA, octanol and the emulsifier, a rutile rougher concentrate assaying 71.3% TiO 2 was floated at 81.6% recovery from a feed containing 8.78% Ti0 2 …

Rutile is a relatively stable mineral, due to its weakly specific adsorption to collectors. The development and application of a high efficiency and low-toxicity activator is the main challenge in rutile flotation. In this study, Al 3+ ions and EDTA (ethylene diamine tetraacetic acid) as mixed activators were investigated using micro-flotation ...
