Major and trace elements data generated on 4 iron ore deposits (Daitari, Jajang, Joda East and Kalta) of Iron Ore Group of Orissa have been processed by using R-mode factor analysis. Total 10 elemental variables are expressed in terms of 3 common rotated factors to understand the mineralogical signatures and processes of metal formation and distribution in the ore. Three distinct processes have been identified: (1) formation of rich iron ores by weathering and erosion with simultaneous removal of silica and development of aluminium bearing minerals, (2) development of nickeliferous ferruginous laterites and (3) accumulation of residual Pb. Bivariate discriminant analysis has been applied to distinguish any pair of deposits of the 4 areas under investigation which are geochemically alike. A combination of 10 elements Fe2O3-SiO2-Al2O3-Ni-Zn-Cu-Co-Cr-Mn-Pb can establish linear discriminant function for any pair without misclassification error.
