Zinc smelting - Wikipedia

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 ...

Safety/Danger of Grinding Galvanized Metal

Feb 01, 2011  Zinc melts at about 790 °F and boils to vapor at about 1650 °F. Therefore zinc oxide vapor can absolutely be created by grinding galvanized steel without "melting" the base metal in a welding operation or otherwise. The likelihood of producing the zinc vapor in significant quantities goes up with reduced thickness of the workpiece.
