- W2371536779 abstract "To use microwave digestion technique for pretreating the uranium ore sample is studied. Under the condition of high pressure seal of ore sample, the main factors influencing microwave digestion (such as power of microwave, pressure, time of digestion, mass of sample, etc)are examined. The digestion conditions are optimized by the orthogonal test analyses and the optimum working conditions and methods of microwave digestion are determined. As the uranium content of ore is 0.02%～2.00%,the uranium in digestion solution can be determined by ammonium vanadate volumetric method, the RSD is less than 5%,recovery of uranium is 98%～100%.The main impurity elements in digestion solution can be determined with conventional chemical analysis and spectrophotometry. The method is certified by determination of standard samples, the analytical results are in agreement with standard values. The research results show the microwave digestion technique can be applied to pretreatment of minerals. The method is simple and rapid. It has less contamination, low energy consumption and obvious social and economic benefits." @default.
