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 …

In this study, benzhydroxamic acid (BHA) was used as the collector for the flotation of fine rutile particles, and water with nanobubbles (NBs) was used to pretreat the particles. Adsorption capacity and zeta potential tests were used to elucidate the mechanism behind the interaction between the rutile and NBs. A high-speed camera was used to observe …

Froth flotation of rutile - An overview. Rutile (TiO 2 ), ilmenite (FeTiO 3) and titanite (CaTiSiO 5) are considered as the most important titanium minerals, particularly rutile, is believed to be the principal source because of its high added value of products. The conventional methods used for concentrating rutile include gravity, magnetic ...

Abstract. The flotation separation of fine minerals, including rutile, has long been a challenging research focus. This study selected rutile and garnet samples with …

Such flotation technique has the potential to be used in industry. However, this method has not yet been applied in a rutile flotation system. To this end, this …

The flotation and surface interaction of rutile with nonyl hydroxamic acid were investigated in this work. The resultsshow that theadsorptiondensityandflotationrecoveryof rutile have …

The petrographical, crystal-chemical and petrogenetical aspects of rutile rich in antimony (up to 33.75 wt.% Sb2O5; equal to 0.2 Sb5+ per O = 2) from St. Marcel-Praborna in the Aosta Valley, Italy ...

In artificially mixed mineral flotation tests, the total weight of feed was 3.0g with the ratio na of rutile to almandine being 1:4 (0.6 of Rutile+2.4g of almandine).The typical flotation experiment was performed as follows: the sample of either rutile or almandine was placed into the flotation cell ur and deionized water added and stirred for ...

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 ...

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 ...

Minerals that commonly occur with monazite are apatite, quartz, ilmenite, rutile, and zircon, 7 which are ideally separated via froth flotation. This is done by slurrying ground ore into an ...

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.

These have two implications for us: (1) Bi3+ ions have the same functional configuration with respect to the activation of Pb2+ ions; (2) Bi3+ ions have been hydrolyzed in the optimal flotation pH of 2–3. We found that Bi3+ ions could significantly improve the recovery rate of rutile flotation in pure minerals.

Results are presented which indicate the effect of pH and flotation-collector type upon the flotation rates of natural rutile particles. Above pH ∼2.5, flotation rate decreases with increasing pH for anionic collectors and increases with increasing pH for a cationic collector. These results are in agreement with expectations from the known electrokinetic …
