摘要：

According to characteristics of the ion absorbing type rare earth ore in-situ leaching process, the ore leaching liquor cannot be fully recovered, and percolation mother liquor and some residual ammonia nitrogen enters the groundwater and surface water constantly, causing an increase in concentration of ammonia nitrogen. Through the study on ammonia nitrogen fate and the resolving process in ion adsorbing type rare earth ore in-situ leaching technology, the in-situ leaching process of water washing to reduce the concentration of ammonia nitrogen is proposed, to repair the ammonia nitrogen pollution sites and to reduce the pollution to groundwater and surface water of the mining area.
