Minerai de nickel<\/strong><\/p>\n

Le nickel est un \u00e9l\u00e9ment chimique dont le symbole est Ni et le num\u00e9ro atomique 28. Il s'agit d'un m\u00e9tal blanc argent\u00e9 brillant avec une l\u00e9g\u00e8re teinte dor\u00e9e. Nickel<\/a> est un m\u00e9tal de transition dur et ductile. Le nickel est un \u00e9l\u00e9ment m\u00e9tallique indispensable dans le monde. C'est une mati\u00e8re premi\u00e8re essentielle pour la fabrication militaire, la fabrication de machines, l'\u00e9nergie atomique, les ultrasons et la communication.<\/p>\n

Les principaux min\u00e9raux du minerai de nickel sont pentlandite, minerai de nickel silico-magn\u00e9sien, goethite ou minerai de nickel jaune, minerai de nickel rouge, etc.<\/strong> Les r\u00e9serves de nickel dans les nodules de mangan\u00e8se des fonds marins sont tr\u00e8s importantes, ce qui constitue une ressource potentielle importante de nickel.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Traitement des minerais de nickel<\/h2>\n\t
\n\t\t
\n\t\t\t

Il existe de nombreux types de minerais de nickel, principalement divis\u00e9s en minerai de sulfure de cuivre-nickel<\/strong> et minerai d'oxyde de cuivre-nickel<\/strong> selon les propri\u00e9t\u00e9s min\u00e9rales. Parmi eux, on peut citer cuivre<\/a> est le principal min\u00e9ral d'impuret\u00e9 dans le minerai de nickel, suivi de plomb<\/a>, le zinc<\/a>l'arsenic, le fluor, mangan\u00e8se<\/a>Le processus d'enrichissement du minerai de sulfure de cuivre-nickel et du minerai d'oxyde de nickel est \u00e9galement un processus d'enrichissement primaire. Dans le processus d'enrichissement, l'enrichissement du minerai de sulfure de cuivre-nickel et du minerai d'oxyde de nickel est \u00e9galement l'enrichissement primaire.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Minerai de sulfure de cuivre-nickel<\/strong> La m\u00e9thode d'enrichissement est principalement flottation<\/strong>et s\u00e9paration magn\u00e9tique et s\u00e9paration par gravit\u00e9<\/strong> sont g\u00e9n\u00e9ralement des m\u00e9thodes d'enrichissement auxiliaires. Collecteurs et agents moussants<\/strong> pour la flottation des min\u00e9raux de sulfure de cuivre sont souvent utilis\u00e9s dans la flottation des minerais de sulfure de cuivre-nickel.<\/p>\n

 <\/p>\n

1. Flottation prioritaire directe (ou partielle)<\/h4>\n

Il s'agit de s\u00e9lectionner le minerai de cuivre pour en faire un concentr\u00e9 s\u00e9par\u00e9, principalement utilis\u00e9 pour les minerais \u00e0 forte teneur en cuivre. La principale caract\u00e9ristique de cette m\u00e9thode est qu'elle permet d'obtenir directement un concentr\u00e9 de cuivre \u00e0 faible teneur en nickel.<\/p>\n

2. Flottation mixte<\/h4>\n

Le proc\u00e9d\u00e9 de flottation mixte convient \u00e0 la s\u00e9paration du minerai dont la teneur en cuivre est inf\u00e9rieure \u00e0 celle du nickel. Le concentr\u00e9 contenant du cuivre et du nickel sera fondu en matte de nickel \u00e0 haute teneur.<\/p>\n

3. Flottation \u00e0 priorit\u00e9 mixte<\/h4>\n

La flottation mixte permet d'extraire le cuivre et le nickel du minerai, puis de s\u00e9parer le nickel \u00e0 faible teneur et le concentr\u00e9 de cuivre \u00e0 faible teneur de la concentration mixte. Le concentr\u00e9 de nickel apr\u00e8s fusion permet d'obtenir la matte de nickel \u00e0 haute teneur, puis la matte de nickel \u00e0 haute teneur est s\u00e9par\u00e9e par flottation.<\/p>\n

4. Flottation \u00e0 priorit\u00e9 mixte et r\u00e9cup\u00e9ration des r\u00e9sidus<\/h4>\n

Apr\u00e8s la flottation, r\u00e9cup\u00e9rer les min\u00e9raux de nickel qui sont moins flottables dans les r\u00e9sidus lorsque les divers min\u00e9raux de nickel sont plus flottables dans le minerai.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>

Traitement des minerais d'oxyde de nickel<\/h3><\/div><\/div>\n\t
\n\t\t
\n\t\t\t

Les gisements d'oxyde de nickel sont relativement peu profonds, id\u00e9aux pour une exploitation \u00e0 ciel ouvert \u00e0 grande \u00e9chelle, et peuvent \u00eatre exploit\u00e9s de mani\u00e8re s\u00e9lective. Apr\u00e8s l'extraction, l'oxyde de nickel est fondu et enrichi, principalement par la pyrom\u00e9tallurgie et l'hydrom\u00e9tallurgie<\/strong>.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t
