Ilmenite is weakly magnetic mineral sand, grey-black in color, solid in form, and exists in a triangle crystal structure. On the other hand, rutile is reddish-brown in color and exists in a tetragonal crystal structure. These heavy mineral sands are excavated and dredged, mostly to commercially produce ilmenite, rutile or other titanium-oxide ...

Therefore mineral ilmenite is used as a source of the Ti02. Various pyrometallurgical and hydrometallurgical processes are used for up-gradation of ilmenite to synthetic rutile or titania slag (Heinz 1997, Tathavadkar et al. 2004). In most of the processes used for production of synthetic rutile, ilmenite mineral is oxidized in first step
