The demand for pure uranium compounds for various applications in the defense and power sectors is continually rising. Consequently, this study investigates the processing of an indigenous uranium ore containing albite (Na2.00Al2.00Si6.00O16.00), boltwoodite (Na2.00K2.77U3.00Si6.00O9.00H4.00), thorite (Th4.00Si4.00O16.00), and quartz (Si6.00O6.00) in a sodium carbonate medium to obtain uranylUranyl pregnant leach solutionPregnant leach solution (UPLS). The experimental test parameters such as lixiviant concentration, reaction temperature, and particle size on the extent of uranium ore dissolution were investigated for optimal uranium extractionUranium extraction conditions.
