O l\u00edtio \u00e9 um elemento valioso para a produ\u00e7\u00e3o de vidro, produtos de alum\u00ednio e baterias. \u00c9 extra\u00eddo de min\u00e9rios de petalite (LiAl(Si2O5)2, lepidolite K(Li,Al)3(Al,Si,Rb)4O10(F,OH)2, espodumena LiAl(SiO3)2 e tamb\u00e9m de salmouras subterr\u00e2neas. A Austr\u00e1lia e o Chile s\u00e3o os maiores produtores mundiais de l\u00edtio.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Rela\u00e7\u00e3o com a explora\u00e7\u00e3o mineira<\/h2><\/div><\/div>\n\t

\n\t\t\t

O l\u00edtio foi descoberto pela primeira vez no mineral petalite. A lepidolite e o espodum\u00e9nio s\u00e3o outros minerais comuns que cont\u00eam l\u00edtio. As quantidades comerciais destes tr\u00eas minerais encontram-se num dep\u00f3sito especial de rocha \u00edgnea a que os ge\u00f3logos chamam pegmatite. Nos pegmatitos, o magma arrefece t\u00e3o lentamente que os cristais t\u00eam tempo para crescer muito. Como a lepidolita \u00e9 um tipo de mica, os seus cristais crescem em folhas longas e finas.<\/p>\n

Os recursos de l\u00edtio s\u00e3o pormenorizados nos resumos de produtos minerais do USGS.<\/p>\n

Extra\u00e7\u00e3o de l\u00edtio:<\/p>\n

O l\u00edtio \u00e9 frequentemente recuperado a partir de salmoura, ou \u00e1gua com uma elevada concentra\u00e7\u00e3o de carbonato de l\u00edtio. As salmouras subterr\u00e2neas aprisionadas na crosta terrestre s\u00e3o a principal fonte de carbonato de l\u00edtio. A extra\u00e7\u00e3o destas fontes \u00e9 menos dispendiosa do que a de rochas como o espodum\u00e9nio, a petalite e outros minerais que cont\u00eam l\u00edtio.<\/p>\n

A produ\u00e7\u00e3o de l\u00edtio em salmoura come\u00e7a por bombear a salmoura para tanques de evapora\u00e7\u00e3o. Ao longo de 12 a 18 meses, a concentra\u00e7\u00e3o da salmoura aumenta para 6.000 ppm de Li atrav\u00e9s da evapora\u00e7\u00e3o solar. Quando o cloreto de l\u00edtio atinge a concentra\u00e7\u00e3o ideal, o l\u00edquido \u00e9 bombeado para uma instala\u00e7\u00e3o de recupera\u00e7\u00e3o e tratado com carbonato de s\u00f3dio, precipitando o carbonato de l\u00edtio, que \u00e9 depois filtrado, seco e expedido.<\/p>\n

\n\t\t
\n\t\t\t

Os compostos de l\u00edtio s\u00e3o utilizados em cer\u00e2mica e vidro, na produ\u00e7\u00e3o de alum\u00ednio prim\u00e1rio, no fabrico de lubrificantes e massas lubrificantes, propulsores de foguet\u00f5es, s\u00edntese de vitamina A, soldas de prata, dispositivos de flutua\u00e7\u00e3o subaqu\u00e1tica e, cada vez mais, em baterias.<\/p>\n

As baterias de l\u00edtio est\u00e3o a revelar-se uma alternativa eficaz e acess\u00edvel \u00e0s baterias tradicionais, bem como a novas aplica\u00e7\u00f5es de baterias. Mais de 50% de l\u00edtio extra\u00eddo \u00e9 utilizado em baterias. Recentemente, esta utiliza\u00e7\u00e3o aumentou rapidamente, o que levou a um aumento da extra\u00e7\u00e3o de l\u00edtio para fornecer o l\u00edtio para as baterias.<\/p>\n

O l\u00edtio \u00e9 misturado com outros metais leves, como o alum\u00ednio e o magn\u00e9sio, para formar ligas fortes e leves (uma liga \u00e9 uma mistura de metais).<\/p>\n

Algum l\u00edtio, sob a forma de carbonato de l\u00edtio ou citrato de l\u00edtio, \u00e9 utilizado como medicamento para tratar a gota (inflama\u00e7\u00e3o das articula\u00e7\u00f5es) e para tratar doen\u00e7as mentais graves.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
