China Has Paid a High Price for Its Dominance in Rare Earths
China's dominance in the rare earth industry has come at a significant environmental and health cost, particularly in regions like Baotou in Inner Mongolia. The Weikuang Dam, an artificial lake containing toxic sludge from rare earth processing, has caused severe pollution, with contaminants seeping into the groundwater and causing health issues. Efforts to clean up have been ongoing but are complicated by lax oversight and government censorship, as well as logistical challenges due to the scale of pollution. Despite some progress, such as reinforced berms and relocation of affected communities, significant environmental risks remain, particularly from radioactive thorium. The complexity is further exacerbated by the intertwined interests of provincial governments and major industrial players like the Baogang Group, which complicates regulatory efforts and transparency.
Dive Deeper:
China's rare earth industry has resulted in significant environmental damage, especially in Baotou, where the Weikuang Dam holds toxic sludge from rare earth processing, leading to groundwater contamination with heavy metals and radioactive substances.
The sludge generated from rare earth processing contains dangerous levels of lead, cadmium, and thorium, which pose serious health risks to the local population, including intellectual development disorders in children.
Efforts to mitigate the environmental impact have been undertaken by the government, such as reinforcing berms and moving residential communities, but challenges persist due to the vastness of the contaminated area and inadequate infrastructure.
The intertwined interests of the Inner Mongolia provincial government and Baogang Group, a major player in the rare earth industry, complicate effective regulatory oversight and transparency, with instances of censorship of pollution discussions.
Despite some signs of improvement, such as cleaner air and the implementation of waste treatment processes, the handling of radioactive thorium remains unclear, and logistical challenges in managing the waste persist.
Illegal mining and pollution in south-central China have historically contributed to environmental degradation, with efforts since 2010 to address these issues costing billions of dollars.
The geopolitical aspect of rare earths, crucial for technologies like fighter jets and missiles, adds further complexity, with China restricting exports of certain rare earths amid trade disputes.
