摘要

Due to the increase in global demand for lithiumLithium, mainly for use in Li-ion batteries, mineral deposits with a low percentage of lithiumLithium compared to the metal contained in brine deposits have been explored. The main disadvantage of separating lithiumLithium from these deposits is the long processing time. For this reason, the separation of solid species containing lithiumLithium by flotation has recently been evaluated. This work characterizes the superficial nature by XRD, indicating that the mineral consists of a single majority phase of lepidoliteLepidolite. TheScanning Electron Microscopy (SEM) SEM–EDS images show particlesParticle of irregular morphology, rounded, and flake-shaped. The EDS indicates that it contains 60.07% oxygen, 16.04% silicon, 10.35% aluminum, 5.76% potassium, 7.62% fluorine, and 0.16% calcium. Infrared analysis detects the main covalent bonds of Si–O, Li–O, Al–O, and K–O present in the lepidoliteLepidolite mineral located at 6925 cm–1, 464 cm–1, 751 cm–1, and 801 cm–1.
