Abstract: Experimental study of strong basic anion exchange resin adsorption removing uranium and limestone eliminate removing uranium tail liquid acid were done on groundwater which polluted by acid in situ leach uranium mining mine radioactivity, the result indicated, indexes of ph value、V and TFe came up to or almost to the permissible criteria of Ⅳ class groundwater of groundwater through two-stage treatment, indexes of Eh、U、Al came up to range of background value.

Key words: Acid in situ leach uranium mining, Groundwater, Ion exchange, Limestone fluidized bed
