Quantitative determination of haematite and chalcopyrite in metamorphic rocks using infrared spectroscopy

The infrared spectroscopic analysis of metamorphic rock samples from Mamandur multimineral complex was investigated. Infrared spectra (4000 cm(-1) to 200 cm(-1)) were obtained for 24 samples collected from different sites and altitudes of Mamandur hills. The observed results show the presence of quartz, microcline feldspar, sillimanite, magnetite, haematite, chalcopyrite and sphalerite minerals. The presence of the peak at 695 cm(-1) confirms the crystallinity of quartz. The quantitative analysis of iron bearing mineral (haematite) and copper bearing mineral (chalcopyrite) yields an average amount of 14.9% and 4.6% respectively.
