As a source of titanium dioxide pigment, rutile is used in plastics, paper products, paints, sunscreen, and even food coloring. Certain welding equipment also uses it. Return to Minerals Database. Rutile is the most common and stable form of titanium dioxide found in nature. It forms under high pressure and high temperature in igneous and.

Then, two stages of spiral chute separation tests were performed to treat the complex rutile ore. A rough zircon concentrate containing 33.18% ZrO2was obtained after the first-stage spiral chute and a rough rutile concentrate containing 56.77% TiO2was obtained after the second-stage spiral chute.

The rutile ore used in this study was obtained from Donghai, Jiangsu province, China. The raw ore was blended and riffled thoroughly to prepare sub-samples for mineralogy analysis. The results of an X-ray fluorescence chemical analysis of the ore sample are presented in Table 1.

Natural rutile is relatively pure titanium dioxide, generally containing more than 95% titanium dioxide.It is an important mineral raw material for extracting titanium, but it has less reserves in the earth's crust. Artificial rutile refers to the use of chemical processing methods. Ilmenite is the most important titanium ore and the main source of titanium …

In nature, titanium dioxide mainly occurs in three structural states: rutile, anatase and brookite (Fig. 2).Together they form the TiO 2 end-member of the ternary system FeO–Fe 2 O 3 –TiO 2 (Fig. 3).Rutile crystallises in the tetragonal space group P4 2 /mnm and is the most common phase, with unit cell parameters a = 4.594 Å and c = …

For leaching experiments, rutile ore was ground to ensure its particle size smaller than 0.074 mm. In each test, 15 g of the ore sample was used for acid leaching in a water bath under the conditions of solid–liquid ratio of 1/6, reaction temperature of 60 °C, reaction time of 4 h, and rotation speed of 500 r/min.

The recovery of pure rutile mineral flotation at the optimum conditions reached 97.5%, and that one for the mixed ore flotation, was higher than 97% with a rutile content of over 80% being achieved (Sun et al., 2010). By the way, it was reported that TPRO can chemically absorb onto rutile surface in the form of chelation, and the …

The rutile grains closer to ore also are zoned and contain V-rich portions in which V contents are >0.2% (commonly >0.4%) whereas barren rutile generally contains <0.15% V. Niobium. contents of >0 ...
