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.

In our study, chlorination of rutile ore (powder, <150 m, 93.29%) was carried out. Temperatures of 1073 1273 K were chosen as reaction temperatures. The total pressure of 102.1 kPa inside the reactor was kept. The combinations of chlorine with solid carbon were used for chlorination. The main objective of this study is to understand the ...

Rutile, the most abundant of three naturally occurring forms of titanium dioxide (TiO2; see also anatase; brookite). It forms red to reddish brown, hard, brilliant metallic, slender crystals, often completely surrounded by …

Rutile presents a wide range of size, texture, and chemical zoning. Rutile is the dominant TiO 2 polymorph in orogenic gold mineralization.
