EFFECT OF PARTICLE SIZE ON THE ALKALINE LEACHING BEHAVIOR OF LOW-GRADE URANIUM ORE
Abstract
A detailed study has been conducted to investigate the leaching behavior of low-grade secondary type, uranium minerals under alkaline conditions. Uranium mapping analysis indicated the significance of each particle size to the leaching process. Owed to its significance, particle size effects were examined by two different experimental schemes: classical plate agita tion and bottle roll te sting. Other infl uencing variables such as agitation time and concentration of used lixiviants, were also considered. Results showed an obvious increase in recove ry with time, however this trend was far from being linear. Conversely, differences in particle dimensions indicated a more involved phenomena.
