清水淋洗对稀土矿原地浸矿工艺残留矿体中浸矿剂去除效果研究

Study on Ore Leaching Reagents Removal Effect in Residual Ore Body of In-situ Leaching Process of Rare Earth Ore by Clean Water Washing

离子型稀土矿山原地浸矿过程会有大量浸矿剂残留矿体中,如治理不当会造成周边水环境氨氮浓度升高,本研究通过实验室淋洗实验,验证清水淋洗去除矿体中残留浸矿剂的效果,为稀土矿山水污染防治提供研究支撑。

In the in-situ leaching process of ion-type rare earth mine,there will be a large amount of ore leaching reagents in residual ore body,if not properly treated,the concentration of ammonia nitrogen in the surrounding water will be growing,laboratory columnar leaching experiments were established to demonstrate the effectiveness environmental protection measures on removal of ore leaching reagents using clean water washing.It provides research support for the prevention and control of water pollution in rare earth mines.
