STUDY ON TREATMENT OF PALUA NON-WEATHERED URANIUM ORES BY AGITATION LEACHING METHOD

Abstract

    This paper present the results of non - weathered uranium ores processing byagitation leaching method. The effects of ore size, oxidation, leaching time, acidconsumption on uranium recovery efficiency have been investigated. The results ofinvestigation show that the suitable parameters for uranium ore leaching were: oresize ≤ 75 μm, oxidation consumption 4 kg/ton, acid consumption 50-55 kg/ton,leaching time 21 h. The uranium recovery efficiency reached > 85%.

Key worlds: non-weathered uranium ore, agitation leaching method
