Aiming at the problems of poor heap leaching permeability, low molybdenum leaching rate and difficult solid-liquid separation in stirring leaching of low-grade uranium-molybdenum ore in Guyuan, a process path of "mixing acid curing-low temperature roasting" synergistic enhanced acid heap leaching was proposed, and the key parameters such as acid concentration, curing temperature and time, roasting temperature and time, and spray intensity were optimized under column leaching conditions. Considering the energy consumption and process effect, the recommended conditions are as follows：ore particle size is -1 mm, acid mixing mass fraction is 12%, curing at 90 ℃ for 3 h, roasting at 300 ℃ for 30 min, acidizing water mass concentration is 10 g/L, spray intensity is 76 L/(m²·h). Under these conditions, the leaching rate of molybdenum slag can reach 82.89%, the molybdenum grade of tailings is reduced to 0.038%, and the uranium grade is reduced to 100.33×10^-6. The results of multi-batch ore verification test show that the process flow has adaptability to uranium-molybdenum ore with fluctuating grade and property. The molybdenum leaching rate of different low-grade uranium-molybdenum ore is stable at 72.51%–77.37%, which can achieve the process goal. The research results can provide technical support for the efficient extraction of low-grade complex uranium-molybdenum ore resources.

针对沽源低品位铀钼矿堆浸渗透性差、钼浸出率低及搅拌浸出固液分离困难等问题，提出“拌酸熟化—低温焙烧”协同强化酸法堆浸的工艺路径，并在柱浸条件下优化了拌酸浓度、熟化温度与时间、焙烧温度与时间及喷淋强度等关键参数。综合考虑能耗与工艺效果，推荐条件为：矿石粒度-1 mm，拌酸质量分数12%，90 ℃熟化3 h，300 ℃焙烧30 min，酸化水质量浓度10 g/L，喷淋强度76 L/（m²·h）。在该条件下，钼渣计浸出率可达82.89%，尾渣钼品位降至0.038%、铀品位降至100.33×10^-6。多批次矿石验证试验结果表明，该工艺流程对品位和性质波动的铀钼矿石具有一定适应性，不同低品位铀钼矿的钼浸出率稳定在72.51%~77.37%，能够实现工艺目标。研究结果可为低品位复杂铀钼矿资源的高效提取提供技术支撑。
