| Resumo: | This review examines the geological and physicochemical properties of Verdete, a potassium-rich rock formation from the Serra da Saudade region (Minas Gerais state, Brazil), and evaluates its viability as a sustainable source of potassium for fertilizer production. The review discusses the composition of Verdete, characterized by mineral associations including glauconite, illite, and quartz, and highlights its potential nutrient profile, which consists of essential elements such as K, Mg, and Ca. The review focuses on various beneficiation methods, emphasizing thermal treatments, acid and alkaline leaching, biological and hydrometallurgical processes that have shown promise in optimizing potassium recovery. By synthesizing recent advancements in the field, this study aims to provide insights into the future of potassium extraction techniques, the environmental implications of mining practices, and the role of Verdete in sustainable agriculture. The findings suggest that further research and technological innovation are essential to maximize the economic and ecological benefits of Verdete as a potassium source. |
