Abstract Scope |
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 uranyl pregnant 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 extraction conditions. At established leaching conditions (2.5 mol/L Na2CO3, 75 °C, 75 µm), an 82.5% dissolution rate was achieved within 120 minutes of retention time. The estimated activation energy (Ea) of 43.44 kJ/mol affirms an eco-feasible chemical mechanism for optimal uranium extraction. Thus, the UPLS obtained was subsequently treated and beneficiated to produce an industrially acceptable uranium compound for defined domestic and industrial uses. |
