Se destaca la monacita, un mineral con torio radiactivo, como posible vía. El texto evalúa si esa alternativa es viable.","fuente":"ieee","fuenteNombre":"IEEE Spectrum","color":"#00629b","autor":"Glenn Zorpette","url":"https://spectrum.ieee.org/monazite-rare-earth","imagen":"https://spectrum.ieee.org/media-library/a-single-earth-moving-vehicle-drives-on-a-terraced-area-in-a-surface-mine.jpg?id=68422625&width=980","tema":"internacional","subtemas":["tierras raras","geopolitica","china","monacita","cadenas de suministro"],"entidades":["China","América del Norte","Australasia","Europa","IEEE Spectrum"],"formato":"dato","entretenimiento":false,"pubTs":"2026-10-15T14:53:02.000Z","indexTs":"2026-10-22T04:37:56.220Z","hash":"85b61a7c84a541b451102512a6b3964afe7bd922b385c041f3f9052481246f1d","tsa":{"time":"Oct 22 04:38:52 2026 GMT","provider":"freetsa.org","sobre":"sello"},"stats":{"views":0,"likes":0,"clicks":0,"dwell":0},"tipo":"motor","registro":"hallazgo","porQueImporta":"China controla cerca del 90 por ciento del mercado de tierras raras, insumo de semiconductores, pantallas y imanes permanentes.

Hundreds of mining companies, government agencies, and industrial facilities scattered across North America, Australasia, and Europe are striving to wrest share from Chinese firms, which control roughly 90 percent of the markets for rare-earth oxides and rare-earth metals. Rare earths are the ingredients on which vast and crucial manufacturing categories depend: semiconductors , LEDs , lasers, displays, metal alloys, optical lenses, and catalysts for petroleum and chemical processing. Most important, though, are permanent magne","pubDate":"Thu, 15 Oct 2026 14:53:02 +0000","url":"https://spectrum.ieee.org/monazite-rare-earth"},"indexado":"2026-10-22T04:37:56.220Z"}}
