The current relevance of lithium use in the manufacture of electric vehicles and portable equipment has generated an increasing demand for this metal, arousing the worldwide interest for its extraction and beneficiation. Therefore, lithium has quickly become a strategic metal which needs to be further investigated for its maximize use. In this sense, a lithiniferous pegmatite from the northeastern region of Minas Gerais was studied, adjusting its granulometry through comminution processes for a mineralogical analysis by X-ray diffraction. The sample presented in its composition about 42.6% of spodumene, the main ore mineral for lithium, showing the potential of the rocks of this region for subsequent use.
