Min\u00e9rio de n\u00edquel<\/strong><\/p>\n

O n\u00edquel \u00e9 um elemento qu\u00edmico de s\u00edmbolo Ni e n\u00famero at\u00f3mico 28. \u00c9 um metal branco prateado e brilhante com uma ligeira tonalidade dourada. N\u00edquel<\/a> \u00e9 um metal de transi\u00e7\u00e3o duro e d\u00factil. O n\u00edquel \u00e9 um elemento met\u00e1lico indispens\u00e1vel no mundo. \u00c9 uma mat\u00e9ria-prima essencial no fabrico militar, no fabrico de m\u00e1quinas, na energia at\u00f3mica, nos ultra-sons e nas comunica\u00e7\u00f5es.<\/p>\n

Os principais minerais do min\u00e9rio de n\u00edquel s\u00e3o pentlandite, min\u00e9rio de n\u00edquel de sil\u00edcio e magn\u00e9sio, goethite ou min\u00e9rio de n\u00edquel amarelo, min\u00e9rio de n\u00edquel vermelho, etc.<\/strong> As reservas de n\u00edquel nos n\u00f3dulos de mangan\u00eas no fundo do mar s\u00e3o muito grandes, o que constitui um importante recurso de prospe\u00e7\u00e3o de n\u00edquel.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Existem muitos tipos de min\u00e9rio de n\u00edquel, divididos principalmente em min\u00e9rio de sulfureto de cobre-n\u00edquel<\/strong> e min\u00e9rio de \u00f3xido de cobre-n\u00edquel<\/strong> de acordo com as propriedades minerais. Entre eles, cobre<\/a> \u00e9 o principal mineral de impureza no min\u00e9rio de n\u00edquel, seguido por chumbo<\/a>, zinco<\/a>ars\u00e9nio, fl\u00faor, mangan\u00eas<\/a>antim\u00f3nio, bismuto, cr\u00f3mio, etc. No processo de beneficiamento, o min\u00e9rio de sulfeto de cobre-n\u00edquel e o min\u00e9rio de \u00f3xido de n\u00edquel s\u00e3o tamb\u00e9m os principais beneficiamentos.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Min\u00e9rio de sulfureto de cobre-n\u00edquel<\/strong> o m\u00e9todo de beneficia\u00e7\u00e3o \u00e9 principalmente flota\u00e7\u00e3o<\/strong>e separa\u00e7\u00e3o magn\u00e9tica e separa\u00e7\u00e3o por gravidade<\/strong> s\u00e3o normalmente m\u00e9todos auxiliares de beneficia\u00e7\u00e3o. Colectores e agentes espumantes<\/strong> para a flota\u00e7\u00e3o de minerais de sulfureto de cobre s\u00e3o frequentemente utilizados na flota\u00e7\u00e3o de min\u00e9rios de sulfureto de cobre-n\u00edquel.<\/p>\n

 <\/p>\n

1. Flota\u00e7\u00e3o priorit\u00e1ria direta (ou parcial)<\/h4>\n

Trata-se de selecionar o min\u00e9rio de cobre num concentrado separado, utilizado principalmente em min\u00e9rios com elevado teor de cobre. A principal carater\u00edstica deste m\u00e9todo \u00e9 que pode obter diretamente concentrado de cobre com baixo teor de n\u00edquel.<\/p>\n

2. Flota\u00e7\u00e3o mista<\/h4>\n

O processo de flota\u00e7\u00e3o mista \u00e9 adequado para separar o min\u00e9rio que tem um grau de cobre inferior ao n\u00edquel. O concentrado com cobre e n\u00edquel ser\u00e1 fundido em matte de n\u00edquel de alto grau.<\/p>\n

3. Flota\u00e7\u00e3o de prioridade mista<\/h4>\n

A mistura de flota\u00e7\u00e3o do cobre-n\u00edquel do min\u00e9rio, em seguida, separa o n\u00edquel de baixo grau e o concentrado de cobre de baixo grau da concentra\u00e7\u00e3o da mistura. O concentrado de n\u00edquel ap\u00f3s a fundi\u00e7\u00e3o obt\u00e9m o mate de n\u00edquel de alta qualidade e, em seguida, utiliza a flutua\u00e7\u00e3o para separar o mate de n\u00edquel de alta qualidade.<\/p>\n

4. Flota\u00e7\u00e3o de prioridade mista e recupera\u00e7\u00e3o de rejeitos<\/h4>\n

Ap\u00f3s a flota\u00e7\u00e3o, recuperar os minerais de n\u00edquel que s\u00e3o menos flutuantes nos rejeitos quando a variedade de minerais de n\u00edquel \u00e9 mais flutuante no min\u00e9rio.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>

Ap\u00f3s a extra\u00e7\u00e3o, o \u00f3xido de n\u00edquel \u00e9 fundido e enriquecido, principalmente por pirometalurgia e hidrometalurgia<\/strong>.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t
