Zinc

Zinc

Zinc is a chemical element with the symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed.

Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).

The third most developed transition metal by humans, zinc is best known for its good resistance to corrosion, from industrial steels to roofing.

ZINC PROPERTIES
Pure zinc is able to combine with oxygen and other non-metals. The action of dilute acids on zinc releases dihydrogen. Its oxidation state is +2. With different ambient elements, the zinc surface reacts and forms a patina that dulls its shine but is adherent and protective.

 

ZINC USES
Most zinc is used to galvanise other metals, such as iron, to prevent rusting. Galvanised steel is used for car bodies, street lamp posts, safety barriers and suspension bridges.
Large quantities of zinc are used to produce die-castings, which are important in the automobile, electrical and hardware industries. Zinc is also used in alloys such as brass, nickel silver and aluminium solder.
