Hematite is the mineral form of iron (III) oxide (Fe2O3). Hematite crystallizes in the rhombohedral system and it has the same crystal structure as limonite and corundum. According to Russell and Ramaswamy and Venkatachalapathy were observed the absorption frequencies of Hematite is explained well. It observed almost in the entire samples which shows peak at 536 cm1 which is the characteristic peak of hematite. The peak of hematite is due to FeAO stretching mode vibration. In all these samples, the intensities of the hematite peaks are weak to medium. Hence this mineral can be considered as trace mineral, thus the
inhalation of such small grain sized iron bearing mineral (hematite)
along with other minerals will also create lung disease,
because the particles are coated in the surface of lungs. Inhalation
of Hematite may cause siderosis, iron pneumoconiosis, hematite
pneumoconiosis, iron pigmentation of the lung. It is technically
used to make it ore of iron, pigment etc.
