O zinco (Zn) \u00e9 fr\u00e1gil, mas torna-se male\u00e1vel a 100\u00b0 C. O zinco, um elemento met\u00e1lico cinzento-azulado, \u00e9 um condutor de eletricidade moderadamente bom. A liga mais comum \u00e9 o lat\u00e3o, que \u00e9 uma mistura de zinco e cobre.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

O zinco \u00e9 recuperado a partir de uma s\u00e9rie de minerais de zinco diferentes. O mais importante deles \u00e9 a esfalerite. Outros minerais, como a smithsonite (ZnCO3, carbonato de zinco) e a zincite (ZnO, \u00f3xido de zinco) s\u00e3o tamb\u00e9m min\u00e9rios de zinco.<\/p>\n

O zinco tamb\u00e9m \u00e9 reciclado a partir de sucata.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

O zinco liga-se bem a outros metais, resultando em metais mais fortes e mais duros. O lat\u00e3o, por exemplo, \u00e9 uma mistura de cobre e zinco 20%-45%.<\/p>\n

Quantidades adequadas de zinco s\u00e3o essenciais para uma vida saud\u00e1vel em todos os seres humanos e animais. \u00c9 necess\u00e1rio para o funcionamento de uma s\u00e9rie de enzimas diferentes. Tamb\u00e9m foi provado que \u00e9 necess\u00e1rio para o crescimento da pele e dos ossos, bem como para a matura\u00e7\u00e3o sexual. O corpo utiliza o zinco para processar alimentos e nutrientes. Quando os animais n\u00e3o t\u00eam zinco suficiente nos seus sistemas, precisam de consumir mais 50% de alimentos para igualar o ganho de peso de um animal com zinco suficiente no seu corpo. Cerca de 0,003% de zinco \u00e9 necess\u00e1rio para uma sa\u00fade adequada.<\/p>\n

O zinco \u00e9 relativamente pouco reativo no ar ou na \u00e1gua. Por conseguinte, \u00e9 aplicado em camadas finas a produtos de ferro e a\u00e7o que precisam de ser protegidos contra a ferrugem. Este processo \u00e9 designado por galvaniza\u00e7\u00e3o. A galvaniza\u00e7\u00e3o \u00e9 efectuada de v\u00e1rias formas. Geralmente, o metal \u00e9 mergulhado em zinco fundido. Tamb\u00e9m pode ser feita por galvanoplastia ou por pintura sobre uma camada de composto de zinco.<\/p>\n

O zinco \u00e9 utilizado no fabrico de borracha e tintas, em produtos qu\u00edmicos, em aplica\u00e7\u00f5es agr\u00edcolas, na ind\u00fastria da borracha, em ecr\u00e3s de televis\u00e3o, em l\u00e2mpadas fluorescentes e em pilhas secas. As moedas de um c\u00eantimo s\u00e3o feitas de zinco - com uma fina camada de cobre por cima.<\/p>\n

O p\u00f3 de zinco \u00e9 utilizado na remo\u00e7\u00e3o de impurezas da solu\u00e7\u00e3o na electrolavagem do zinco.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
