原地浸析采矿中的溶液毛细损失及其对策

Capillary Loss of Solution during the in Situ Leach Mining and the Countermeasure

室内试验和现场观测分析探讨了离子型稀土矿实施原地浸析采矿时所发生的溶液毛细上升现象， 及因毛细之升所造成的采场内稀土资源与浸出电解质药剂的损失， 提出了避免毛细上升损失的在采场内人工降雨及加大顶水高度的对策。实践证明，采用这两种对策，可最大限度地减少毛细损失，取得良好效益。

Indoor experiment and in-field observation analyzes and explores the capillarity of solution during the in situ mining at the ion-absorbed rare earth mine, and the loss of solution and mineral caused by it, and presents the countermeasure to avoid it by artificial rain in the mining field or increase the level of the push-water. It is proved by practice that the two way is the effective.
