摘要: 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.
