Processes such as solid–liquid extraction, solvent extraction, and ion exchange are applied to obtain pure triuranium octaoxide (U3O8) from uranium ore [1]. Since in most of uranium minerals uranium is accompanied by other heavy metals, post-leaching liquors usually contain a mixture of different metal ions that should be separated from UO22+.
