extraction of titanium dioxide from ilmenite ore. Leaching of ilmenite ores by acidic chloride solutions . The leaching results of both ilmenite ore samples A and B confirm that direct leaching with HCl at high Cl − concentration ( 500 g/L) is very effective to treat ilmenite ore for the extraction of titanium and iron.
· In this study, TiO2 nanoparticles have been obtained from lowgrade ilmenite ore via two consecutive acid digestion and solvent extraction processes. The asextracted TiO2 (Anatase phase) product was characterized using techniques such as XRD, XRF, FESEM, FTIR and BET surface area. Diluted sulfuric acid and D2EHPA (bis(2ethylhexyl) phosphoric acid) were used as digester agent .
Titanium dioxide (TiO2) is derived from ilmenite a mineral found in the metamorphic, plutonic igneous rocks and beach sands in India. It can be classified into anatase, rutile and brokite, of which only anatase and rutile are commercially important. TiO2 is consumed across paints, plastics, paper and many other end use segments. The titanium Di .

· The present investigation relates to a process for producing different phases of titanium dioxide from lowgrade ilmenite ore. The process includes a novel combination of HCl leaching, solvent extraction of iron and hydrothermal treatment to economically produce a high purity grade titanium dioxide. 2. Materials and Materials. A representative .
· Titanium Ore Extracting Flowsheet. The flowsheet shown was developed for a mixed rutile and ilmenite ore containing some magnetite. Concentration in this typical case starts at about 10 mesh and continues on into the minus 200 mesh fines. Gravity concentration starting as coarse as possible is very important in the recovery of a mixed ore of rutile and ilmenite, .

The extraction of titania from ilmenite (ore or mineral) was the subject of numerous studies [6, 8, 3, 11, 13]. Most of these studies were concerned with the extraction of titania from ilmenite by H2SO4 and HCl, whereas few ones were directed to extraction of titania by interaction with alkaline reagents [9, 1, 7]. Sulfate process and chloride ...
Solutions of ilmenite (FeTiO 3) and a titaniferous slag, in fused Li 2 O. 2B 2 O 3 and Li 2 O. 4B 2 O 3, yield on cooling compounds tentatively identified as LiFe 2. 5 Ti 3 O 9 and Li 2 Fe 3 Ti 2. 5 O 9 respectively. Both compounds are orthorhombic, and have the pseudobrookite structure. The ilmenite solutions yield, in addition, rutile (TiO 2).The yield of rutile increases from about 1 to 24% ...
