Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific ...

Zinc - PUB2897 | Missouri Department of Natural Resources

Commodity Zinc is a brittle, whitish metal used in a wide range of industries, most familiarly as a galvanizing material for steel. Known and used for millennia, it was named "zinc" in the early 1500s by Paracelsus, a Swiss physician and philosopher. The name was derived from "zinke," a German word for "fork tooth," referring to the form zinc often took when smelted.
