Feldspato \u00e9 o nome dado a um grupo de minerais que se distinguem pela presen\u00e7a de alumina e s\u00edlica (SiO2) na sua qu\u00edmica. Este grupo inclui silicatos de alum\u00ednio de soda, pot\u00e1ssio ou cal. \u00c9 o grupo de minerais mais abundante na Terra. Representam cerca de 60% de rochas expostas, bem como solos, argilas e outros sedimentos n\u00e3o consolidados, e s\u00e3o componentes principais em esquemas de classifica\u00e7\u00e3o de rochas. Os minerais inclu\u00eddos neste grupo s\u00e3o os feldspatos ortoclase, microclina e plagioclase.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Os principais Estados produtores de feldspato s\u00e3o a Carolina do Norte, a Virg\u00ednia, a Calif\u00f3rnia, o Oklahoma, o Idaho, a Ge\u00f3rgia e o Dakota do Sul, por ordem decrescente de tonelagem estimada. Os transformadores de feldspato comunicaram a recupera\u00e7\u00e3o de co-produtos como a mica e a areia siliciosa.<\/p>\n

O feldspato \u00e9 extra\u00eddo de grandes corpos gran\u00edticos (chamados plut\u00f5es pelos ge\u00f3logos), de pegmatitos (formados quando os \u00faltimos est\u00e1gios fluidos de um granito em cristaliza\u00e7\u00e3o se concentram em pequenas bolsas ricas em l\u00edquido e vapor que permitem o crescimento de cristais extremamente grandes) e de areias compostas principalmente de feldspato.<\/p>\n

Uma vez que o feldspato \u00e9 um componente t\u00e3o importante da crosta terrestre, presume-se que a oferta de feldspato \u00e9 mais do que suficiente para satisfazer a procura durante muito tempo. As actuais minas em todo o mundo est\u00e3o a satisfazer adequadamente as necessidades de feldspato bruto.<\/p>\n

A extra\u00e7\u00e3o de feldspato em rocha dura \u00e9 feita por m\u00e9todos a c\u00e9u aberto, quer pelo propriet\u00e1rio da mina quer por empreiteiros. Depois de o min\u00e9rio de feldspato ter sido perfurado e dinamitado, a quebra secund\u00e1ria \u00e9 efectuada com uma bola de queda convencional. O min\u00e9rio \u00e9 ent\u00e3o carregado com uma p\u00e1 hidr\u00e1ulica em cami\u00f5es e transportado para a instala\u00e7\u00e3o de tritura\u00e7\u00e3o, que fica adjacente \u00e0 instala\u00e7\u00e3o de flota\u00e7\u00e3o.<\/p>\n

Utiliza\u00e7\u00f5es: O feldspato \u00e9 utilizado para fabricar lou\u00e7a e azulejos de casa de banho e de constru\u00e7\u00e3o. Na produ\u00e7\u00e3o de cer\u00e2mica e vidro, o feldspato \u00e9 utilizado como fundente. O fundente \u00e9 um material que reduz a temperatura de fus\u00e3o de outro material, neste caso, o vidro.<\/p>\n

Substitutos e fontes alternativas<\/p>\n

O feldspato pode ser substitu\u00eddo por outros minerais e misturas de minerais com propriedades f\u00edsicas semelhantes. Os minerais que podem ser utilizados para substituir o feldspato incluem a pirofilite, as argilas, o talco e as misturas de feldspato e s\u00edlica (quartzo). A abund\u00e2ncia de feldspato tornar\u00e1 estas substitui\u00e7\u00f5es desnecess\u00e1rias num futuro previs\u00edvel.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
