A Look At Rare Earth Metals And Their Applications

Rare earth metals are actually not as rare as their name might imply. Critical to highperformance optics and lasers and key to the most powerful magnets and superconductors in the world, rare earths are simply more difficult to mine than most metals and generally don't accumulate into rich ores.The Geology of Rare Earth Elements Republished from: The resulting alkaline magmas are rare and unusually enriched in elements such as zirconium, niobium, strontium, barium, lithium, and the rare earth elements. into deposits known as placers.
