Removal of Residual Ammonium from Weathered Crust Elution-Deposited Rare Earth Ore Tailings by Magnesium Chloride: Kinetics and Mass Transfer

After in situ leaching of weathered crust elution-deposited rare earth ore (WREO), large amounts of residual ammonium (RA) salts remain in the ore body and slowly release, causing persistent ammonia-nitrogen pollution in surrounding waters. This study proposes using magnesium chl...
