2019-5-14 · Rutile Titanium Flotation Processing. Description of titanium and rutile. Rutile deposit can be divided into metasediment, eclogite, hydrothermal alteration, metamorphic altered rock and weathering-sedimentation. Natural rutile is the high-quality raw material for producing titanium dioxide, titanium sponge, titanium tetrachloride series products.
2018-7-26 · Rutile (TiO2) is a vital industrial material used in pigments and in many other valuable chemicals. A new production process to synthesize rutile from natural ilmenite ore and therefore overcome the environmental problems associated with conventional rutile extraction processes was developed. Because the simple phase separation of ilmenite (FeTiO3) into Fe2O3 and
Then, the oxidation experiment was conducted in air using Australian ilmenite ore to obtain rutile as one of the coexistent phases. Magnetic separation and leaching experiments for synthesized pseudobrookite and reagent rutile were conducted to confirm the possibility of separation of rutile from pseudobrookite.
