Boom in Mining Rare Earths Poses Mounting Toxic Risks
By Mike Ives • January 28, 2013. In November, the first shipment of raw "rare earth" minerals arrived at an $800 million processing plant on Malaysia's east coast near the home of Tan Bun Teet. The plant, run by Australia's Lynas Corporation, has since begun refining the rare earth metals, essential components in wind turbines, hybrid ...
