Abstract: In order to meet the development of the a large magmatic shaped-type ilmenite resources，the research on the process mineralogy of a representative ore was carried out.Results show that:①The main useful minerals are ilmenite and magnetite in ilmenite ore，secondary titanium containing mineral is titanite，and gangue minerals are mainly amphibole and pyroxene.②Coarse ore ilmenite are closely associated with magnetite and sphene，and the size of three aggregates mainly concentrated in the 0.5 ~ 0.1 mm.With the solid solution isolating structure，fine，microfine ilmenite and sphene are distributed in pyroxene，hornblende and biotite in general，with particle size less than 0.004 mm.③That the titanium-containing minerals like amphibole and pyroxene，and ilmenite，titanite exist in a very fine particle isolating structure of solid solution is the main reason for lowering TiO₂ recoveries.④ As many as 54.42% of iron element exists in silicate，carbonate and metal sulfide is the main reason for low iron recovery.The ilmenite ore belongs to refractory ilmenite ore.
