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.
