Abstract:
Lithium, one of the so-called “critical minerals”, defined in the National Mining Plan 2030, has gained prominence in academic research and the mineral industry in recente Years. Its most importante deposits are found in brines and pegmatites, the latter a hard rock with important occurrences in Brazil. In this work, pegmatites from Eastern Minas Gerais, classified as albite-spodumene type, the main variety of pegmatite for lithium ore, had their main minerals and mineral associations characterized by several analytical techniques: steromicroscopy, X ray diffraction, X ray fluorescence, X ray micro-fluorescence, optical emission and laser ablation spectrometries, in order to identify the main lithiferous phases, and the amount of lithium contained in different minerals
