Introduction au minerai de coltan<\/h2>\n

L'exploitation mini\u00e8re du coltan joue un r\u00f4le incompatible avec l'industrie mini\u00e8re. Le coltan est largement utilis\u00e9 dans la fabrication de produits de haute technologie, tels que les t\u00e9l\u00e9phones portables, les lecteurs de DVD, les jeux PS2, etc.<\/p>\n

Les minerais de tantale-niobium comprennent le tantale et le niobium. Lorsque le tantale est le plus abondant, on parle de tantalite, lorsque le niobium est le plus abondant, on parle de niobite. Il existe des minerais de tantale-niobium alluvionnaires et des minerais de tantale-niobium pierreux.<\/p>\n

Processus d'extraction du coltan<\/h2>\n

Alimentation<\/strong>Le syst\u00e8me d'alimentation : il existe plusieurs types de m\u00e9thodes d'alimentation, en fonction des conditions de l'usine et du mat\u00e9riau. Il est possible de choisir entre un alimentateur vibrant, une tr\u00e9mie, un alimentateur \u00e0 bande ou une chargeuse sur roues et une excavatrice qui alimentent directement l'usine.<\/p>\n

Tamisage<\/strong>Le proc\u00e9d\u00e9 : ce proc\u00e9d\u00e9 consiste \u00e0 laver des \u00e9chantillons \u00e0 l'aide d'un crible \u00e0 vibration et \u00e0 les cribler en fonction de leur taille. Le crible vibrant peut ajouter de l'eau \u00e0 haute pression, ce qui permet de laver l'\u00e9chantillon. Le crible peut obtenir deux tailles, la grande taille \u00e9tant destin\u00e9e au concasseur \u00e0 c\u00f4ne et la petite taille au s\u00e9parateur \u00e0 jig.<\/p>\n

Broyeur<\/strong>: La taille de sortie du concasseur \u00e0 c\u00f4ne est plus petite que celle du concasseur \u00e0 m\u00e2choires, du concasseur \u00e0 marteaux, et la taille de sortie du concasseur \u00e0 c\u00f4ne a \u00e9galement besoin d'un alimentateur pour le s\u00e9parateur \u00e0 jig.<\/p>\n

S\u00e9parateur \u00e0 sas<\/strong>: Il dispose de deux voies d'alimentation, l'une apr\u00e8s le s\u00e9parateur \u00e0 tamis vibrant de petite taille, et l'autre apr\u00e8s le concasseur \u00e0 c\u00f4ne de taille de sortie. Le s\u00e9parateur Jig dispose \u00e9galement de deux voies de concentration, l'une pour la concentration vers le haut de l'\u00e9cran, l'autre pour la concentration vers le bas de l'\u00e9cran.<\/p>\n

Table \u00e0 secousses<\/strong>: La table \u00e0 secousses est utilis\u00e9e pour la concentration finale, apr\u00e8s le s\u00e9parateur \u00e0 jig, on passe \u00e0 la table \u00e0 secousses. La table \u00e0 secousses sert \u00e0 am\u00e9liorer le contenu, parfois si le contenu n'est pas \u00e9lev\u00e9, il n'est pas n\u00e9cessaire d'utiliser la table \u00e0 secousses.<\/p>\n

Le diagramme de processus le plus efficace et l'\u00e9quipement de processus le plus appropri\u00e9 sont toujours recommand\u00e9s en fonction de la demande du client, des conditions du minerai de tantale-niobium et de la capacit\u00e9 du processus.
