Description
Lithium, an important raw material for battery production, is mainly extracted from lithium-containing minerals. This work focuses on the analysis of lithium-containing minerals (spodumene, amblygonite and lepidolite) using a Raman spectrometer. The lithium-containing samples are excited at different wavelengths to determine whether useful Raman signals are produced and at which excitation wavelengths. In addition, the influence of the lithium content in spodumene samples on the Raman signals is analyzed. The investigations prove that the Raman spectrometer is an effective tool for the identification of minerals. The evaluation of the behavior of the lithium content in the Raman spectrum has shown that the intensity of the Raman spectra does not depend solely on the concentration.
