Liquid ion exchange processes are crucial in hydrometallurgical metal recovery, and successful operation depends on reagents exhibiting fast phase separation rates. This paper presents a phase separation test designed to evaluate liquid ion exchange reagents, specifically the copper reagent LIX®64N. The methodology is implemented using a laboratory apparatus consisting of a Pyrex glass test chamber equipped with impellers for stirring the feed liquor. The test's reproducibility was confirmed over a year of study with a low standard deviation, indicating reliability in determining phase separation times. Results indicated the test is adaptable for evaluating carrier solvents, quality control of other reagents, and for comparative analysis between different reagents. Consequently, this test could establish a standardized method for assessing the performance of liquid ion exchange systems in metallurgical applications.
