The major world ilmenite deposits are located in: America, Africa, =
Australia, India and elsewhere the deposits can occur as beach sands or =
as massive ore bodies. The composition of ilmenite ores varies in TiO=B2 =
from 38% to more than 60 %, the lower concentration predominantly =
occurring in the massive deposits while the richer ilmenite is usually =
found in alluvial deposits and in these cases in association with other =
heavy minerals such as rutile, zircon and monazite.
The ilmenite ores are recovered from alluvial deposits along with other =
heavy minerals including rutile while it is mined and concentrated from =
the massive deposits. Typical composition of titania bearing sources are =
listed in the following tables for ilmenite ores and rutile =
respectively.
