    A process for treating ilmenite to obtain a beneficiated product having a relatively high titanium dioxide content. Particulate ilmenite is first heated in the presence of a reducing agent to reduce the iron compounds in the ilmenite to ferrous oxide and/or metallic iron. The resulting product is then leached with a dilute inorganic acid to solubilize the reduced iron values.
