Ilmenite is weakly magnetic mineral sand, grey-black in colour, solid in form and exists in a triangle crystal structure. On the other hand, rutile is reddish-brown 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 ores.Web
