Spectro radiometry and Hyperspectral remote sensing to Characterise the iron ores of Singhbhum iron ore belt india

Abstract

Demand for iron ore has taken off in recent years led by rising newlinesteel production in the industries which indicate a rising demand for iron newlineores there by necessitating the adoption of rapid and accurate approaches to newlineiron ore exploration and grade assessment There has been a need to find new newlinemethods other than the conventional methods which will make the newlineexploration easier and cost effective thereby necessitating the adoption of newlinerapid and accurate approaches to iron ore exploration and grade assessment It newlineis in this context that hyperspectral radiometry and remote sensing is seen as a newlinepotential tool newlineThis thesis addresses this issue and examines the potential of the newlineVisible NIR and SWIR energy of the EMR in differentiating iron ores of newlinedifferent grades in a rapid manner using hyperspectral radiometry This thesis newlinealso examines the potential of hyperspectral satellite images in iron ore newlinemapping and grade estimation in the Noamundi and Joda mines Jharkhand newlineand Orissa states of India Using different iron ore samples from the study newlineregion certain spectro radiometric measurements and geochemical analysis newlinewere carried out and the results have been presented From the spectral newlinemeasurements it is seen that the landcover ground features in general and newlineiron ores in particular show their characteristic reflectance and absorption newlinespectra The strength of reflectance and absorption at definite wavelength newlineregion is controlled by the chemical composition of the iron ores newline newline
