| Abstract Scope |
The extraction of lithium from lepidolite, a lithium-bearing mica mineral, is gaining importance due to the rising demand for lithium-ion batteries. This study investigates the effectiveness of direct acid leaching using hydrochloric acid (HCl) in extracting lithium from lepidolite. Various parameters including acid concentration, leaching temperature, solid-to-liquid ratio, and leaching duration were studied to optimize lithium extraction. Experimental results for lithium extraction efficiency were: 0.1 mol/L HCl, a leaching temperature of 75°C, a solid-to-liquid ratio of 1:10, and a leaching duration of 2 hours, giving a lithium recovery rate of over 70%. Characterization of the leach residue by X-ray diffraction (XRD) and scanning electron microscopy (SEM) revealed minute structural changes and mineralogical transformations. The product as characterized demonstrated that direct acid leaching with hydrochloric acid is a hardly efficient method for effective lithium extraction from a typical lepidolite, thus offering the potential for industrial raw material in lithium-ion batteries. |
