【摘要】 与国外相比,我国的铀水冶工艺有自己的特点和特色。基于铀矿资源矿床规模小、矿体分散、品位低的特点,堆浸是我国天然铀生产的主工艺。通过对我国铀矿冶企业目前采用的堆浸工艺和技术的分析,说明堆浸具有基建投资少、生产成本低、能耗和水耗低的优点。同时也具有适应性差、资源回收率相对较低的缺点。矿石的水冶工艺流程主要是由矿床条件和矿石性质决定的,只有多种流程才能适应不同的矿石要求。为了适应核电对天然铀的需求,基于我国铀资源的现状,必须加强新工艺、新技术、新设备、新材料的研究、开发和应用。更多还原

【Abstract】 Based on small and disperse uranium deposits,and low grade ores,heap leaching has been developed as the dominating technique in the uranium production of China.It is indicated that heap leaching technique has such advantages as less capital,low cost,low power consumption and water consumption.At the meanwhile,heap leaching technique presents shortcomings of poor adaptability and low recovery rate.In order to meet the oncoming enormous demand of nuclear power,great effort shall be put on research of new technology,new equipment,new material.更多还原
