O enxofre (S) \u00e9 um elemento brilhante, amarelo-lim\u00e3o, macio e n\u00e3o met\u00e1lico que tem uma condutividade t\u00e9rmica muito baixa, o que significa que n\u00e3o consegue transferir calor muito bem. O toque de uma m\u00e3o far\u00e1 com que um cristal de enxofre rache porque a superf\u00edcie do cristal aquece mais rapidamente do que o interior. O enxofre derrete a 108 graus Celsius. Enxofre significa \"pedra ardente\" em refer\u00eancia \u00e0 sua origem nos vulc\u00f5es e ao facto de arder t\u00e3o facilmente. Quando o enxofre \u00e9 queimado, combina-se com o oxig\u00e9nio, produzindo di\u00f3xido de enxofre, SO2<\/sub>que tem um cheiro forte e pungente.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

O enxofre liga-se a i\u00f5es met\u00e1licos, criando uma s\u00e9rie de minerais de sulfureto significativos, como a galena (sulfureto de chumbo), a pirite (sulfureto de ferro), a calcocite (sulfureto de cobre) e a esfalerite (sulfureto de zinco). O enxofre extra\u00eddo \u00e9 maioritariamente proveniente de c\u00fapulas de sal ou de dep\u00f3sitos de leitos. A grande maioria \u00e9 produzida como um subproduto da refina\u00e7\u00e3o de petr\u00f3leo e do processamento de g\u00e1s natural.<\/p>\n

A extra\u00e7\u00e3o de enxofre utiliza tr\u00eas t\u00e9cnicas de extra\u00e7\u00e3o diferentes: m\u00e9todos subterr\u00e2neos convencionais, m\u00e9todos convencionais a c\u00e9u aberto e o m\u00e9todo de extra\u00e7\u00e3o Frasch (ou fus\u00e3o subterr\u00e2nea). Neste processo, a \u00e1gua quente \u00e9 for\u00e7ada a entrar no dep\u00f3sito de enxofre. O enxofre derrete e \u00e9 empurrado para a superf\u00edcie onde \u00e9 recolhido e deixado arrefecer e solidificar, ou enviado na forma fundida.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

A maior parte do enxofre produzido nos Estados Unidos \u00e9 utilizada para fabricar \u00e1cido sulf\u00farico. O \u00e1cido sulf\u00farico tem m\u00faltiplas utiliza\u00e7\u00f5es na produ\u00e7\u00e3o de produtos qu\u00edmicos, produtos petrol\u00edferos e uma vasta gama de outras aplica\u00e7\u00f5es industriais. A principal utiliza\u00e7\u00e3o do enxofre \u00e9 no fabrico de produtos qu\u00edmicos para a agricultura, principalmente para fertilizantes. Outras utiliza\u00e7\u00f5es do enxofre incluem a refina\u00e7\u00e3o do petr\u00f3leo, a extra\u00e7\u00e3o de metais e a produ\u00e7\u00e3o de produtos qu\u00edmicos org\u00e2nicos e inorg\u00e2nicos. Uma grande quantidade de produtos (como a produ\u00e7\u00e3o de borracha para pneus de autom\u00f3veis) requer enxofre de uma forma ou de outra durante alguma fase do seu fabrico.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
