Abstract

Four-dimensional trend surface analysis is applied to the geochemical data generated on the drill core samples of the nickeliferous lateritic overburden of South Kaliapani mine to understand the distribution of Ni, Co, Fe2O3, Cr2O3, SiO2 and Al2O3. The distribution can be used to delineate different ore zones which will help in selective mining/removal of overburden, blending and beneficiation of low grade ores depending on the purpose of their use like nickel extraction, development of ferro-nickel and/or ferro-chrome.
