  • Producing a titanium product
    Patent number: 10190191
    Abstract: A method (400) for producing a titanium product is disclosed. The method (400) can include obtaining TiO2-slag (401), and producing a titanium product from the TiO2-slag using a metallic reducing agent (402) at a moderate temperature and a pressure to directly produce a titanium product chemically separated from metal impurities in the TiO2 slag (403). The titanium product can comprise TiH2 and optionally elemental titanium. Impurities in the titanium product can then removed (404) by leaching, purifying and separation to form a purified titanium product.
    Type: Grant

    Date of Patent: January 29, 2019
    Assignee: University of Utah Research Foundation
    Inventors: Zhigang Zak Fang, Peng Fan, Scott Middlemas, Jun Guo, Ying Zhang, Michael Free, Amarchand Sathyapalan, Yang Xia

  • PRODUCTION OF TITANIUM DIOXIDE PIGMENTS
    Publication number: 20150176103
    Abstract: A process includes roasting a TiO2-containing material in the presence of an alkaline material to form a roasted product; leaching the roasted product with an acidic solution to form a leach liquor; extracting the leach liquor with an extractant to form a raffinate including a Ti4+ species; hydrolyzing the Ti4+ species to form a hydrolyzed material that includes H2TiO3; calcining the hydrolyzed material; and recovering a TiO2 product.
