(CNN) Scientists find huge trove of rare metals needed for clean energy hidden inside toxic coal waste. Quoting,

These so-called rare earths are a cluster of metallic elements, with names like scandium, neodymium and yttrium, which exist in the Earth’s core. They have a critical role in clean technology, including electric vehicles, solar panels and wind turbines.

This is FALSE. The rare earth elements are not believed to exist in the core to appreciable degree. They have been concentrated by geochemical processes in the mantle.
