H\u00e1 um velho ditado que diz: \"Se n\u00e3o for cultivado, tem que ser minerado\". Isso n\u00e3o \u00e9 totalmente verdade, mas faz voc\u00ea se perguntar quais itens n\u00e3o se encaixam em nenhuma dessas categorias. Continue lendo para saber mais.<\/strong><\/p>\n\n\n\n

A minera\u00e7\u00e3o foi e sempre ser\u00e1 fundamental para a nossa civiliza\u00e7\u00e3o. Isso \u00e9 especialmente verdadeiro em nossa era impulsionada pela tecnologia, na qual a minera\u00e7\u00e3o de \"elementos de terras raras\" adquiriu um significado especial. \u00c9 prov\u00e1vel que voc\u00ea tenha lido not\u00edcias sobre os elementos de terras raras nos \u00faltimos anos; ent\u00e3o, o que s\u00e3o eles e por que s\u00e3o t\u00e3o importantes?<\/p>\n\n\n\n

Os elementos de terras raras s\u00e3o fundamentais para o nosso mundo moderno.<\/h2>\n\n\n\n

Quando as pessoas pensam em minera\u00e7\u00e3o, geralmente pensam em minera\u00e7\u00e3o de carv\u00e3o, cobre ou ouro, mas todos os tipos de mat\u00e9rias-primas s\u00e3o extra\u00eddos da terra. Por ser t\u00e3o difundido, o setor de minera\u00e7\u00e3o \u00e9 um tema muito debatido entre pol\u00edticos, ambientalistas e comunidades em todo o mundo.<\/p>\n\n\n\n

Mais recentemente, a aten\u00e7\u00e3o voltada para a minera\u00e7\u00e3o de elementos de terras raras cresceu rapidamente em escala e impacto globais. Para come\u00e7ar, h\u00e1 17 minerais de terras raras agrupados na Tabela Peri\u00f3dica de Elementos: c\u00e9rio (Ce), dispr\u00f3sio (Dy), \u00e9rbio (Er), eur\u00f3pio (Eu), gadol\u00ednio (Gd), h\u00f3lmio (Ho), lant\u00e2nio (La), lut\u00e9cio (Lu), neod\u00edmio (Nd), praseod\u00edmio (Pr), prom\u00e9cio (Pm), sam\u00e1rio (Sm), esc\u00e2ndio (Sc), t\u00e9rbio (Tb), t\u00falio (Tm), it\u00e9rbio (Yb) e \u00edtrio (Y). No entanto, apesar de seu nome misterioso, nem todos eles s\u00e3o realmente \"raros\".<\/p>\n\n\n\n

O que os torna t\u00e3o importantes, ou como os chamamos, \"raros\", \u00e9 que esses materiais s\u00e3o encontrados de uma forma ou de outra em praticamente todos os dispositivos tecnol\u00f3gicos do planeta. Sem eles, o mundo moderno como o conhecemos n\u00e3o poderia existir.<\/p>\n\n\n\n

\"\"\/<\/figure>\n\n\n\n

Os elementos de terras raras nos ajudam a \"ficar verdes\".<\/h2>\n\n\n\n

O grande impulso tecnol\u00f3gico no momento \u00e9 \"tornar-se verde\" por meio de ve\u00edculos el\u00e9tricos e fontes de energia sustent\u00e1veis. Um metal de terras raras em particular - o am\u00f3dio - \u00e9 usado para produzir \u00edm\u00e3s fortes para motores el\u00e9tricos e geradores de turbinas. Muitas baterias recarreg\u00e1veis tamb\u00e9m s\u00e3o fabricadas com metais de terras raras, como lant\u00e2nio, c\u00e9rio, prom\u00e9cio e neod\u00edmio.<\/p>\n\n\n\n

Os elementos de terras raras s\u00e3o o futuro.<\/h2>\n\n\n\n

De telefones celulares e motores de aeronaves a m\u00e1quinas de resson\u00e2ncia magn\u00e9tica que salvam vidas todos os dias, os elementos de terras raras s\u00e3o componentes essenciais para a evolu\u00e7\u00e3o da tecnologia e o futuro da inova\u00e7\u00e3o. At\u00e9 o momento, a China \u00e9 o maior produtor de elementos de terras raras, mas isso est\u00e1 come\u00e7ando a mudar. Com o aumento do pre\u00e7o dos metais da China e o crescente reconhecimento entre as pot\u00eancias mundiais de que os elementos de terras raras s\u00e3o recursos estrat\u00e9gicos, muitas outras na\u00e7\u00f5es est\u00e3o aumentando a capacidade de produ\u00e7\u00e3o dom\u00e9stica, tanto para atender \u00e0 demanda crescente quanto para garantir um fornecimento est\u00e1vel.<\/p>\n\n\n\n

Aqui nos EUA, a Polydeck est\u00e1 ajudando uma nova mina em Nevada a produzir metais de terras raras. A Austr\u00e1lia, o Brasil e a \u00cdndia tamb\u00e9m aumentaram a produ\u00e7\u00e3o recentemente.<\/p>\n\n\n\n

O futuro \u00e9 brilhante para os elementos de terras raras e a minera\u00e7\u00e3o deles \u00e9 definitivamente um setor em crescimento no futuro pr\u00f3ximo, desde que continuemos a usar telefones celulares, dirigir carros el\u00e9tricos e usar os dispositivos mais recentes.<\/p>\n\n\n\n
