A Scarcity of Rare Metals Is Hindering Green

Nov 18, 2013China currently dominates rare earth mining — in part, notes a 2011 American Physical Society report, because more relaxed environmental standards about land reclamation make it cheaper. But resources exist elsewhere. There are about 450 potential rare earth mines being looked at around the world, according to King. A few are fairly advanced. Get price
