The infrared spectra of the ore samples in Fig. 1 show some similarities, as expected from their comparable mineral composition, with similar peaks position but at different intensities. In the higher wavenumber region, the peak at 3684 cm −1 is stronger in the ore S than in ores L and I samples. This is due to stretching vibrations of outer …
Hint: The process of separation of iron and the impurities from the iron ore on the basis of density requires the separation based on the difference in specific gravities of the metallic ore and gangue particles present in the ore. Step by step answer: A naturally occurring rock or the sediments in the earth crust which contains valuable minerals in …
