摘要：

To explore the influence of microwave power, irradiation time and other factors on the grinding effect and leaching rate of uranium ores, intermittent microwave pretreatment feasibility was verified via comparison with continuous. The research shows that when the microwave power is 800 W, using continuous microwave pretreatment on granite uranium ore, the irradiation for 120s as the best process parameter, the parameter under 0.15 mm of uranium ore mass fraction is 68.97%, the leaching rate is 72.98%. For intermittent microwave pretreatment, the optimal process parameters are a 30s pulse, an i...
