Contiene torio radiactivo, proveniente sobre todo del procesamiento de la monacita para tierras raras. China ya endureció sus controles sobre esa industria.","fuente":"ieee","fuenteNombre":"IEEE Spectrum","color":"#00629b","autor":"Glenn Zorpette","url":"https://spectrum.ieee.org/china-rare-earth-minerals","imagen":"https://spectrum.ieee.org/media-library/a-body-of-water-with-a-layer-of-solid-matter-on-its-surface-with-industrial-facilities-in-the-background.jpg?id=68422690&width=980","tema":"ciencia","subtemas":["tierras raras","contaminacion","mineria","torio radiactivo","china"],"entidades":["China","Baotou","Mongolia Interior","IEEE Spectrum"],"formato":"dato","entretenimiento":false,"pubTs":"2026-10-15T14:54:03.000Z","indexTs":"2026-10-22T04:37:56.220Z","hash":"4871e01df8a07144e2210f35ad6780e9308576518b5cda6e026ef98151d93f6b","tsa":{"time":"Oct 22 04:38:52 2026 GMT","provider":"freetsa.org","sobre":"sello"},"stats":{"views":0,"likes":0,"clicks":0,"dwell":0},"tipo":"normal","registro":"hallazgo","porQueImporta":"Gran parte de los componentes de celulares, autos eléctricos y turbinas eólicas depende de tierras raras que China procesa casi en exclusiva.

The artificial lake, referred to by the name of the dam associated with it, Weikuang Dam (or Baogang Tailings Dam), has for decades collected the effluent from minerals processing for China’s globally dominant iron, steel, and rare-earths industries. Built in the late 1950s, the lake contains a highly toxic stew of industrial chemicals with substantial amounts of radioactive thorium, the latter resulting primarily from the processing of monazite ores for rare-earths .
