Abstract

This work proposes a method of converting local iron ores into colour pigments to add commercial and technical values to the commodity. Iron ores were subjected to hammer-crushing and two milling techniques (low-energy ball milling and high-energy milling) to produce submicron or ultrafine pigment particles. Effects of different milling duration, speed and charge type on the particle size were investigated. X-ray diffraction and energy-dispersive X-ray spectroscopy scans revealed that the ores contain hematite and goethite phases, with 54% of Fe and 3538% of O. Particle size analysis showed that high-energy milling (14 hours, 11 mm charge, 550 rev min1) was effective in producing particles as small as 1379 m. Commision Internationale de l'Eclairage L∗a∗b∗colour values measured were L∗of 497, a∗of 212 and b∗of 158.
