La mine \u00e0 ciel ouvert\u00a0Mont-Wright<\/a>\u00a0d\u2019ArcelorMittal<\/a>\u00a0fait l\u2019extraction du minerai de fer pour produire du concentr\u00e9.<\/p>\n

Elle est situ\u00e9e \u00e0 17 kilom\u00e8tres \u00e0 l\u2019ouest de\u00a0Fermont<\/a>\u00a0sur la\u00a0C\u00f4te-Nord<\/a>, dans la\u00a0Fosse du Labrador<\/a>.\u00a0Couvrant une superficie de 60 kilom\u00e8tres carr\u00e9s, c\u2019est la plus grande mine \u00e0 ciel ouvert du Qu\u00e9bec.<\/strong><\/p>\n

Ses ressources y sont consid\u00e9rables puisque les r\u00e9serves prouv\u00e9es sont de 5,6 milliards de tonnes de minerai<\/p>\n

En plus de l\u2019exploitation mini\u00e8re, le site du Mont-Wright compte un concasseur, un concentrateur, des ateliers d\u2019entretien, un entrep\u00f4t de pi\u00e8ces et un syst\u00e8me de chargement des trains.<\/p>\n

Suivant le plan d\u2019exploitation, les patrons de forage comportent g\u00e9n\u00e9ralement plus de 360 trous de diam\u00e8tre de 13 pouces sur 15,8 m\u00e8tres de profondeur dans lesquels on verse un m\u00e9lange explosif d\u2019environ 1 300 kg qui sert \u00e0 fracasser le roc (800 000 tonnes de mat\u00e9riel en moyenne par sautage). Ce processus est r\u00e9p\u00e9t\u00e9 3 fois par semaine. Une fois la mati\u00e8re fragment\u00e9e, elle est transport\u00e9e par camion au concasseur qui morcelle la roche \u00e0 environ 30 cm de diam\u00e8tre. Les blocs de minerai sont ensuite achemin\u00e9s par convoyeur au concentrateur o\u00f9 ils sont broy\u00e9s finement et tamis\u00e9s.<\/p>\n

Le concentrateur fonctionne comme une centrifugeuse : l\u2019eau permet de s\u00e9parer gr\u00e2ce \u00e0 la force centrifuge et la gravit\u00e9 les r\u00e9sidus des particules de fer qui sont plus lourdes. Le concentr\u00e9 est achemin\u00e9 au silo de chargement des trains \u00e0 destination de Port-Cartier, tandis que les r\u00e9sidus de silice sont achemin\u00e9s \u00e0 un parc de confinement dont la restauration sera effectu\u00e9e \u00e0 la fin de l\u2019exploitation mini\u00e8re.<\/p>\n

Environ 1400 personnes travaillent actuellement pour l\u2019entreprise ArcelorMittal du c\u00f4t\u00e9 du Mont-Wright.<\/p>\n<\/div>\n
