BENEFICIATION OF ILMENITE ORES - LAPORTE INDUSTRIES

The ilmenite was then fed to a gas-fired rotary kiln, 0.55m. in diameter and 7.3m. in length, at a rate of 45 kg. per hour, and was oxidised in the kiln at 850°C. by means of atmospheric air. The residence time of the ilmenite in the kiln was about 2 hours, and X-ray examination of the oxidised material showed it to comprise 35% by weight pseudobrookite together with rutile and haematite.
