The behaviour of transition metal ions in tetrahedrite and in tennantite have been studied by electron paramagnetic resonance and optical absorption spectroscopy in the UV-Vis and NIR regions. The ground state of Cu(II) ion in both the minerals is confirmed as 2B1g . In both the minerals, two sets of three characteristic bands observed in the optical absorption spectra are assigned to the transitions, 2B1g -> 2A1g, 2B1g ->2B2 and 2B1g ->2Eg of Cu(II) ion in tetragonal field. The presence of Fe(III) bands is an evidence for iron impurity in the tetrahedrite and Mn(II) in tennantite mineral. The copper content in tetrahedrite and tennantite is about 40wt %. The NIR spectra are due to water present in the samples. |
