Abstract
Abstract Placer ilmenites from three deposits of Andhra Pradesh coast have been investigated for their ore mineralogy. The deposits studied are Kakinada, Bhimunipatnam, and Srikurmam. Standard ore mineralogical methodology adopted for the preparation of polished sections of placer ilmenite grains from the three deposits. The detailed study of these sections under reflected light microscope revealed that the ilmenites from Kakinada are devoid of exsolutions whereas the ilmenites from other two deposits have indicated exsolved phases in the grain level textures, these phases are mainly Ilmenau-hematite, hemo-ilmenite and exsolved phases of rutile. The grain level textures or exsolved phases observed are 1) Homogenous ilmenites, 2) Ilmenites with simple Exsolutions, 3) Ilmenites with complex Exsolutions, 4) Irregular forms, 5) Dispersion or emulsion texture, 6) Lamellar Texture, 7) Skeletal Texture, 8) Worm like lamellae 9) Myrmekitic or Graphic Exsolutions and, 10) Alteration textures. Their presence will have implications for the processing of ilmenites. Because of the fact that the hematite phases in the ilmenite grain will make the ilmenite more iron-rich and thus may result from some processing problems as well as reduced titanium recovery.
