In the mineral processing industry, the selective extraction of certain minerals such as uranium, thorium, and vanadium is achieved through solvent extraction processes that involve bringing two immiscible phases into contact for effective mass transfer. This study describes the fundamental processes and the design of a multi-stage counter-current solvent extraction plant tailored for uranium extraction and purification, focusing on the operational circuits: extraction, water wash, stripping, and solvent scrubbing. Each circuit is detailed, illustrating the separation of the desired minerals from aqueous solutions using organic solvents under controlled parameters including pH and temperature. A specific case study of the solvent extraction plant based on the Eluex process at Agnew Lake Mine provides insights into the practical challenges faced, such as the frequent maintenance of mixer tanks and the need for regular calibration of instruments used in the extraction and precipitation circuits. Additionally, routine maintenance requirements highlight the operational efficiency and reliability of standard industrial components within the extraction system. Overall, the findings contribute to a deeper understanding of the operational dynamics in solvent extraction circuits, emphasizing the importance of parameters that ensure the purity and recovery efficiency of targeted minerals.
