Galvanizing is a process for rustproofing iron and steel by the application of a zinc coating. Three of the most-used processes for applying zinc to iron and steel are hot-dip galvanizing, electrogalvanizing, and zinc spraying. Most products are coated using the hot-dip process. It involves immersing steel into a bath of molten zinc,

During the actual galvanizing step of the process, the material is completely immersed in a bath of molten zinc. The bath chemistry is specified by ASTM B6, and requires at least 98% pure zinc maintained at approximately 840 F (449 C). While immersed in the kettle, the zinc reacts with the iron in the steel to form a

Zinc is used in the production of corrosion-resistant alloys and brass, and for galvanizing steel and iron products. Zinc oxide, used in rubber as a white pigment, for example, is the most widely used zinc compound. Peroral zinc is occasionally used to treat zinc deficiency in humans. Zinc carbamates are used as pesticides (1). ANALYTICAL METHODS

$2.1 billion. Zinc was mined in six States at 15 mines operated by five companies. Two smelter facilities, one primary and one secondary, operated by two companies, produced commercial-grade zinc metal. Of the total reported zinc consumed, most was used in galvanizing, followed by brass and bronze, zinc-based alloys, and other uses.
