Extraction of titanium dioxide (TiO2) from ilmenite and ...

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% ...
