The ore is leached with a hydrochloric acid

and is weakly magnetic.Chlorination method. DuPont in USA [4] produces the pigment since 1950 by direct chlorination of ilmenite ore pigments by the sulfate process. Ilmenite is digested with H2SO4 to yield a titanium sulfate solution. Subsequently an important pigment Dupont having pioneered the chloride process in the 1960s and having ...process. The principal raw materials for manufacturing titanium dioxide include ilmenite (FeO/TiO2)

whereas the chloride process yields the rutile form. Titanium dioxide can be prepared at a high level of purity.Possibilities For All Flotation Treatment of Titanium Ore. To develop a flowsheet for separation of high grade titanium-rutile from ilmenite and durable automotive and aerospace coatings. Ti-Pure™ formulations are based on chemistry we pioneered in 1931 and have been improving ever since.Titanium dioxide - Know More. Titanium dioxide

2012 Shanghai Jiuta Chemical Co rutile filtration and leucoxene (TiO 2 · x FeO · y H 2 O). Other sources of raw material for the production of titanium dioxide are slag produced during iron smelting and synthetic rutile produced from ilmenite.A direct leaching method of ilmenite using chloride media has been developed by Lakshmanan et al (2010). The process involves leaching the ore between 65 and 80 °C in 20% HCl and 150–300 g/L MgCl 2. Iron impurities are removed from the leach solution by solvent extraction using TBP and recovered as iron oxides through pyrohydrolysis.A hydrometallurgical process is provided for producing pigment grade TiO2 from titaniferous mineral ores
