Chasing China’s Monazite Monopoly
The article explores how China controls rare-earth markets through monazite processing, using Baotou's heavily polluted Weikuang Dam as a case study of industrial contamination and radioactive waste. China has since restricted new monazite mining due to environmental damage. As Western nations invest billions to diversify rare-earth supply chains, they must reckon with the environmental and regulatory challenges that monazite processing presents, drawing on China's cautionary experience.
Key points
- China controls ~90% of rare-earth oxide and metal markets via monazite processing
- Weikuang Dam in Inner Mongolia contains toxic industrial waste and radioactive thorium
- China banned standalone monazite mining due to environmental concerns
- Western nations seeking supply-chain independence must address same environmental challenges
