\n\t\t\t

Le zinc (Zn) est cassant, mais il devient mall\u00e9able \u00e0 100\u00b0 C. Le zinc, un \u00e9l\u00e9ment m\u00e9tallique bleu-gris, est un moyennement bon conducteur d'\u00e9lectricit\u00e9. L'alliage le plus courant est le laiton, qui est un m\u00e9lange de zinc et de cuivre.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Relation avec l'exploitation mini\u00e8re<\/h2><\/div><\/div>\n\t
\n\t\t
\n\t\t\t

Le zinc est r\u00e9cup\u00e9r\u00e9 \u00e0 partir d'un certain nombre de min\u00e9raux de zinc diff\u00e9rents. Le plus important d'entre eux est la sphal\u00e9rite. D'autres min\u00e9raux, tels que la smithsonite (ZnCO3, carbonate de zinc) et la zincite (ZnO, oxyde de zinc) sont \u00e9galement des minerais de zinc.<\/p>\n

Le zinc est \u00e9galement recycl\u00e9 \u00e0 partir de d\u00e9chets.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

<\/div>

Utilisations<\/h2><\/div><\/div>\n\t
\n\t\t
\n\t\t\t

Le zinc s'allie bien avec d'autres m\u00e9taux, ce qui permet d'obtenir des m\u00e9taux plus r\u00e9sistants et plus durs. Le laiton, par exemple, est un m\u00e9lange de cuivre et de zinc 20%-45%.<\/p>\n

Des quantit\u00e9s ad\u00e9quates de zinc sont essentielles \u00e0 une vie saine chez tous les humains et les animaux. Il est n\u00e9cessaire au fonctionnement d'un certain nombre d'enzymes. Il a \u00e9galement \u00e9t\u00e9 prouv\u00e9 qu'il \u00e9tait n\u00e9cessaire \u00e0 la croissance de la peau et des os, ainsi qu'\u00e0 la maturation sexuelle. L'organisme utilise le zinc pour transformer les aliments et les nutriments. Lorsque les animaux n'ont pas assez de zinc dans leur syst\u00e8me, ils doivent consommer 50% de nourriture en plus pour atteindre le gain de poids d'un animal ayant suffisamment de zinc dans son corps. Environ 0,003% de zinc est n\u00e9cessaire pour \u00eatre en bonne sant\u00e9.<\/p>\n

Le zinc est relativement peu r\u00e9actif dans l'air ou dans l'eau. C'est pourquoi il est appliqu\u00e9 en fines couches sur les produits en fer et en acier qui doivent \u00eatre prot\u00e9g\u00e9s de la rouille. Ce proc\u00e9d\u00e9 s'appelle la galvanisation. La galvanisation s'effectue de diff\u00e9rentes mani\u00e8res. En g\u00e9n\u00e9ral, le m\u00e9tal est plong\u00e9 dans du zinc en fusion. Elle peut \u00e9galement \u00eatre r\u00e9alis\u00e9e par galvanisation ou par application d'une couche de compos\u00e9 de zinc.<\/p>\n

Le zinc est utilis\u00e9 dans la fabrication du caoutchouc et de la peinture, dans les produits chimiques, dans les applications agricoles, dans l'industrie du caoutchouc, dans les \u00e9crans de t\u00e9l\u00e9vision, dans les lampes fluorescentes et dans les piles s\u00e8ches. Les centimes sont fabriqu\u00e9s en zinc, recouvert d'une fine couche de cuivre.<\/p>\n

La poussi\u00e8re de zinc est utilis\u00e9e pour \u00e9liminer les impuret\u00e9s de la solution dans l'extraction \u00e9lectrolytique du zinc.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
