A halite, vulgarmente conhecida como sal de mesa ou sal-gema, \u00e9 composta por cloreto de s\u00f3dio (NaCl). \u00c9 essencial para a vida dos seres humanos e dos animais. O sal \u00e9 utilizado na prepara\u00e7\u00e3o de alimentos em todo o mundo.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Extra\u00e7\u00e3o de sal-gema:<\/p>\n

Muitas minas de sal-gema utilizam o m\u00e9todo de extra\u00e7\u00e3o subterr\u00e2nea \"room-and-pillar\", no qual o recurso \u00e9 extra\u00eddo, deixando \"pilares\" do material intactos, o que cria \"salas\".<\/p>\n

Minera\u00e7\u00e3o de solu\u00e7\u00f5es:<\/p>\n

A minera\u00e7\u00e3o por solu\u00e7\u00e3o envolve a inje\u00e7\u00e3o de um solvente para dissolver e recuperar minerais de sal sol\u00faveis no subsolo. A salmoura saturada \u00e9 bombeada para a superf\u00edcie para recupera\u00e7\u00e3o atrav\u00e9s de evapora\u00e7\u00e3o solar e processamento posterior.<\/p>\n

Evapora\u00e7\u00e3o da \u00e1gua do mar:<\/p>\n

A \u00e1gua do mar \u00e9 recolhida e deixada a evaporar em tanques de concentra\u00e7\u00e3o e evapora\u00e7\u00e3o especialmente constru\u00eddos para o efeito. A etapa inicial concentra a salmoura para aumentar a salinidade e permitir que v\u00e1rios compostos de c\u00e1lcio, magn\u00e9sio e ferro precipitem da solu\u00e7\u00e3o. A salmoura circula entre uma rede de tanques interligados alimentados por gravidade, com a salinidade a aumentar em cada transfer\u00eancia. A partir do momento em que a \u00e1gua do mar \u00e9 inicialmente introduzida, s\u00e3o necess\u00e1rios cerca de 2 a 5 anos para que o primeiro sal esteja pronto para ser colhido.<\/p>\n

Evapora\u00e7\u00e3o solar interior:<\/p>\n

Os princ\u00edpios da concentra\u00e7\u00e3o e produ\u00e7\u00e3o de sal solar s\u00e3o semelhantes aos das margens costeiras, com a exce\u00e7\u00e3o de que a salinidade dos lagos interiores \u00e9 geralmente superior \u00e0 da \u00e1gua do mar e pode ser colhida uma colheita anual de sal. \u00c0 medida que a \u00e1gua flui sobre ou sob a superf\u00edcie, dissolve os minerais dos solos e rochas subjacentes. Os lagos salgados s\u00e3o topograficamente mais baixos do que a maioria das \u00e1reas circundantes e, por conseguinte, tornam-se excelentes reservat\u00f3rios para a acumula\u00e7\u00e3o de minerais.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Mais de 40% de sal s\u00e3o utilizados na ind\u00fastria qu\u00edmica (principalmente para a prepara\u00e7\u00e3o de hidr\u00f3xido de s\u00f3dio, carbonato de s\u00f3dio, \u00e1cido clor\u00eddrico, cloro e s\u00f3dio met\u00e1lico) e outros 40% como descongelador de estradas no inverno. O restante \u00e9 consumido em v\u00e1rios sectores, incluindo o fabrico de borracha e outros bens, a agricultura e a transforma\u00e7\u00e3o de alimentos, incluindo o sal de mesa.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
