Basics

An element with an atomic number of 30
Low melting temp metal (420C) which can be used for a stovetop foundry. See Stovetop Metal Casting.
It is very useful, especially for Cathodic Protection either as a sacrificial anode, or via Galvanisation
Some batteries use zinc

USA pennies after 1982 are made from zinc, and weigh either 2.5 or 3.1 grams [1].
Zinc ingot - $3/lb. [2]

1-2 Ton USA sourcing. [3]

Dripping a zince droplet from inside a penny - easy experiment with a torch and pennies. Dropping is nice and pure zinc. [4]

Not cost effective.
It is cost effective to use a small furnace with a steel mesh, so zinc drips out the bottom, and copper shells stay on top. - [5]
