Abstract
Lithium is a highly sought-after resource crucial for rechargeable batteries, and the Kenticha pegmatite ore deposit in Ethiopia holds potential as a source of this valuable element. The focus of this study was to investigate the mineralization of Kenticha, specifically the spodumene ore, and its suitability for beneficiation processes. Through XRD, AAS, and petrographic microscope analysis, the study identified the minerals present in the spodumene pegmatite ore, their average composition, and mineral texture for spodumene concentrate liberation. Spodumene was found to be the most abundant mineral, but its low degree of liberation from other minerals required additional processing steps for high yield. Weathering significantly impacted mineral identification and quantification, affecting diverse mineral morphology and liberation. The study's findings have implications for mining operations, exploration, and processing strategies, suggesting additional processing steps for spodumene recovery and highlighting the impact of weathering on mineral characterization. The study provides valuable information on mineral texture and liberation for selecting processing methods for beneficiation, contributing to a better understanding of the Kenticha pegmatite ore deposit's mineralization potential for lithium extraction.
