摘要
以新疆某砂岩铀矿采区为研究对象,对所有抽注单元的浸出液铀浓度与HCO-3浓度变化关系进行了分析。结果表明:HCO3^-浓度与浸出液铀浓度有着密切的变化关系,大体上可分为6种类型;水动力、水化学、矿化条件、钻孔工程等因素是铀浓度与HCO3^-浓度关系呈现不同特征的主要原因。在生产中充分挖掘和利用铀浓度、HCO3^-变化特征所蕴含的信息是提高CO2+O2地浸采铀精益化管理的重要途径。
Taking a uranium deposit’s mining area in Xinjiang as the research object,the relationship between uranium concentration and HCO3^- concentration in all drawing and injecting units was analyzed.The results show that the concentration of HCO3^- is closely related to uranium leaching results and the variation relation types of uranium leached concentration with HCO3^- concentration can be divided into 6 types.Moreover,the hydrodynamic force,hydrochemistry,mineralization conditions,drilling engineering and other factors are the reasons for the different characteristics of the relationship between uranium concentration and HCO3^- concentration.Therefore,it is an important way to improve the lean management at the production of uranium by CO2+O2 in-situ leaching by fully exploiting and utilizing the information contained in uranium concentration and HCO3^- variation characteristics.
