The method (400) can include obtaining TiO 2 -slag (401), and producing a titanium product from the TiO 2 -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 TiO 2 slag (403). The titanium product can comprise TiH 2 and optionally elemental titanium. Impurities in the titanium product can then removed (404) by leaching, purifying and separation to form a purified titanium product.
