The impact of unregulated ionic clay rare earth mining

2016-6-1 · In-situ leaching can cause serious environmental degradation including soil contamination, water (above and underground) contamination, elevated PH values, mine collapses and landslides. More than 100 landslides were reported in Ganzhou region. These are believed to be caused by in-situ leaching of rare earth ion-absorbed clays.
