Abstract

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%.
