摘要
探讨了提高某铀钼矿铀、钼浸出率的途径,分析了所用浸出工艺的优劣。结果表明,选用的加压碱浸最佳工艺参数为:总碱用量18%,氧分压0.7MPa,温度120℃,液固比1.5∶1,时间3h。铀、钼浸出率均达到89%以上。
The ways to improve leaching rates of uranium and molybdenum from a molybdenum-bearing ura- nium ore were discussed. The leaching process was analyzed in terms its advantage and disadvantage. The results show that alkaline pressure leaching process is selected and the optimum conditions include dosage of alkaline of 18 %, oxygen partial pressure of 0.7 MPa, temperature of 120℃, ratio of liquid to solid of 1.5：1, and time of 3 h. The leaching rate of uranium and molybdenum are both above 89%.
