An improved process for recovering a titanium dioxide product from a titanium oxide-containing roasted mass of the type derived from roasting an ilmenite, anatase or perovskite ore by exploiting an organic acid, such as mixture of oxalic acid and ascorbic acid.
Abstract:
An optical fiber amplifier is formed from glass doped with praseodymium. The glass may include one or more of cadmium mixed halide, hafnium halides, geranium and silicon disulphide based vitreous materials or fluorozirconate glass fibers. It is possible to provide an optical fiber amplifier which operates at a 1300 nm window for passive optical networks
Abstract:
The present invention seeks to improve beneficiation of a titanium oxide-containing composition (such as a low-grade or highly radioactive TiO2 ore) by combining a roasting and selective leaching steps.
