摘要
通过对砂岩型铀矿铀源岩样品中活性铀的浸出试验,选择了相对合理的浸取剂,讨论了样品粒度、固液比、称样量、温度、时间等因素对铀浸出率的影响,拟定了一个适用性广,操作条件较宽松、质量稳定的浸取体系和分析方案。该分析方案对不同类型铀源岩中活性铀的浸出率测量相对标准差小10%(n=11)。
Based on the leaching experiments on mobile uranium from U-source rock samples of sandstone type U-deposits, the reasonable leaching reagent has been selected, and factors which may effect the leaching rate of mobile uranium such as the grain-size of the sample, the solid-liquid ratio, the sample weight, the temperature, and the leaching time etc, have been discussed, and a widely applicable and quality-stable leaching system and analytic scheme have been developed. The relative standard deviation of the method for the measurement of leaching rate of mobile uranium from U-source rocks of different types is less than 10% （n=ll） .
