O termo rocha fosf\u00e1tica (ou fosforito) \u00e9 utilizado para designar qualquer rocha com elevado teor de f\u00f3sforo. A maior e menos dispendiosa fonte de f\u00f3sforo \u00e9 obtida atrav\u00e9s da extra\u00e7\u00e3o e concentra\u00e7\u00e3o de rocha fosf\u00e1tica dos numerosos dep\u00f3sitos de fosfato do mundo. Algumas rochas fosf\u00e1ticas s\u00e3o utilizadas para fabricar suplementos nutricionais de fosfato de c\u00e1lcio para animais. O f\u00f3sforo puro \u00e9 utilizado no fabrico de produtos qu\u00edmicos para utiliza\u00e7\u00e3o na ind\u00fastria. No entanto, a utiliza\u00e7\u00e3o mais importante da rocha fosf\u00e1tica \u00e9 a produ\u00e7\u00e3o de fertilizantes fosfatados para a agricultura. Praticamente todos os fertilizantes comuns t\u00eam uma classifica\u00e7\u00e3o \"N-P-K\". O f\u00f3sforo \u00e9 o \"P\" dos fertilizantes. O f\u00f3sforo est\u00e1 envolvido em numerosas fun\u00e7\u00f5es das plantas, mas o seu papel mais importante \u00e9 ajudar as plantas a captar a energia do sol e a iniciar o processo de fotoss\u00edntese.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

A maior parte da rocha fosf\u00e1tica \u00e9 extra\u00edda por m\u00e9todos de superf\u00edcie em grande escala. No passado, os m\u00e9todos de extra\u00e7\u00e3o subterr\u00e2nea desempenharam um papel mais importante, mas a sua contribui\u00e7\u00e3o para a produ\u00e7\u00e3o mundial est\u00e1 a diminuir. Muitas vezes, as opera\u00e7\u00f5es de extra\u00e7\u00e3o alimentam um complexo de transforma\u00e7\u00e3o de fertilizantes nas proximidades para a produ\u00e7\u00e3o de produtos fertilizantes concentrados a jusante. Atualmente, a maior parte da produ\u00e7\u00e3o de rocha fosf\u00e1tica a n\u00edvel mundial \u00e9 extra\u00edda utilizando m\u00e9todos de extra\u00e7\u00e3o a c\u00e9u aberto com dragline ou p\u00e1\/escavadora. Este m\u00e9todo \u00e9 amplamente utilizado em partes dos Estados Unidos, Marrocos e R\u00fassia.<\/p>\n

Durante a explora\u00e7\u00e3o mineira de superf\u00edcie, a sobrecarga \u00e9 perfurada, rebentada e removida por dragline para o lado da \u00e1rea mineira para posterior recupera\u00e7\u00e3o. Pequenas draglines, p\u00e1s el\u00e9ctricas e bulldozers recuperam a parte superior do min\u00e9rio. A camada intercalada de calc\u00e1rio \u00e9 ent\u00e3o dinamitada e removida para expor o leito de fosfato, que \u00e9 carregado em cami\u00f5es. A extra\u00e7\u00e3o por dragagem utiliza escavadoras com rodas de balde, draglines, raspadores, p\u00e1s e dragas. Os tr\u00eas principais m\u00e9todos de transporte de materiais na extra\u00e7\u00e3o de fosfatos s\u00e3o a bombagem, o transporte por cami\u00e3o e o transporte por correias transportadoras.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
