This report presents a cost analysis of Titanium Dioxide production from leucoxene. The process examined consists of beneficiation of leucoxene to synthetic rutile by the Becher process, followed by a typical chloride process to produce Titanium Dioxide. In this process, leucoxene is oxidized and reduced to convert the iron in its metalic form.
modification. The molecular orbital bonding energy diagram in Figure2clearly shows the fundamental features of anatase TiO2 [18]. The chemical bonding of anatase TiO2 can be deconstructed into Ti, e.g., Ti t2g (dyz, dxz, and dxy), O ps (in the Ti3O cluster plane), and O pp (out of the Ti3O cluster plane).
It involves two stages- Mixing the dry ore with coke and chlorine to form titanium chloride, and then oxidising titanium chloride by burning it in oxygen with another combustible gas.
