China's Rare-Earth Monazite Processing Tied to Toxic Baotou Tailings Lake
A joint Foreign Policy/IEEE Spectrum report details how China's dominance in rare-earth elements relies heavily on monazite ore, much of it from the Bayan Obo mine near Baotou, Inner Mongolia. The report notes that decades of processing monazite for rare earths produced the Weikuang Dam tailings lake, a highly polluted, radioactive site, and that China now bans stand-alone monazite mining due to the environmental damage it caused.
