A plant in Australia processes ilmenite placer ore. The titanium in the ore is mainly ilmenite, followed by rutile, white titanium, brookite, and sphene. 4.91% of titanium is dispersed in iron-manganese minerals (goethite, pyrite, hydrohematite, etc.) and gangue minerals (kaolinite, quartz, feldspar, etc.).
