摘要
离子型稀土原地浸矿采用硫酸铵作浸矿液,浸矿液渗入地下引起地下水氨氮等浓度增加,造成水体污染。根据源头控制、回收利用、监控应急的污染控制思路,提出了清污分流、人工防渗假底、三级监控收液、溪流水回收、监控应急、生态恢复、地下水长期监控等6项污染控制措施,供矿山设计、生产管理、研究人员参考。
When ammonium sulphate as leaching solution is applied in the in-situ leach mining of ion-absorbed rare-earth mineral,the leaching solution permeating underground increases the ammonium concentration in groundwater and pollutes water environment.Based on the pollution control philosophy of controlling source,recycling,monitoring and tackling emergency,six pollution control measures are proposed in this paper as wastewater and clear water separation,manual waterproof false bottom,3-level monitoring and collecting system,stream water recycling,monitoring and tackling emergency,ecological restoration and groundwater long-term monitoring,which can serve as reference for mine design,production management and research work.
