摘要
为了将电动原地浸出(EK-ISL)技术更好地应用于低渗透性铀矿开采,提高低渗透性铀矿的浸出效率,需要借助数值模拟技术对其进行研究。从地浸采铀过程的物理化学行为出发,介绍了数值模拟技术对地浸采铀的推动作用,总结了地浸采铀模型的基本方程和求解方法,结合电动修复领域的相关数值模型分析了EK-ISL模型需要描述的关键过程,并在此基础上提出了初步的电动原地浸出采铀数值模型。
In order to better apply the electrokinetic in-situ leaching(EK-ISL)technology to the mining of low permeability uranium ore and improve the leaching efficiency of low permeability uranium ore,it is necessary to study it with numerical simulation technology.Starting from the physical and chemical behaviors in the process of in-situ leaching of uranium,the promotion of numerical simulation technology to in-situ leaching uranium were reviewed,the basic equations and solving methods of the model of in-situ leaching uranium were summarized,the key processes that need to be described by EK-ISL model were analyzed based on this,a preliminary numerical simulation model of electrokinetic in-situ leaching uranium was proposed.
