| Abstract Scope |
In this work investigated the instrumental characterization of a lepidolite mineral [K(Li,Al)3(Si,Al)4O10(F,OH)2], by laser-induced breakdown spectrometry (LIBS), via chemical analysis by inductively coupled plasma spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy in conjunction with energy dispersive SEM-EDS microanalysis to determine the purity and chemical composition of the mineral. LIBS results reported contents of 7.0% K, 1.2% Li, 8.0% Al, 14.4% Si, 10.7 F, and 58.7% O, all in % by weight. XRD analysis shows that the principal phases present in the mineral are lepidolite (PDF 01-85-0389), quartz (PDF 03-065-0466), and muscovite (PDF 00-006-0263). Micrographs obtained by SEM showed scaly, translucent, foliated aggregate crystals characteristic of the lepidolite mineral. This elemental and species analysis will be used in the subsequent treatment of the mineral via pyrometallurgical process. |
