A metal is sometimes classified as a transition metal but is not strictly. This element is not very abundant in the earth's crust but is obtained with ease. One of its most important applications is galvanized steel. It is an essential element.

It is a bluish-white metal that burns in air with a bluish green flame.

Aplications

• Batteries used in the aerospace industry for missiles and space capsules for optimum yield per unit weight, zinc-air batteries for laptops.
• Castings injected in the automotive industry.
• Metallurgy of precious metals and elimination of silver from lead.
  

Zinc is used in construction as a replacement for lead because it has a low toxicity.

Recycling is widespread in the industry. But as it is mixed with other metals depends on the reuse of the metals with which it has been merged.

Recycling zinc offers both environmental and economic benefits. Saving energy reduces the need for mining and smelting.
Can be recycled repeatedly  and still maintain their physical and chemical characteristics.
