In this work, the possibilities of molybdenum content reduction in uranium leach liquor was investigated by adsorption techniques. Several activated charcoals were used as adsorbents. Under the optimized condition, 83.59% of molybdenum was adsorbed with “Norit PK 0.25-1” activated charcoal. Since the low uranium adsorption is the aim of this work, by performing the optimization conditions, the uranium adsorption with activated charcoal was determined to be 2.74%.
