Zinc smelting WikipediaTechnical Progress of Blast Furnace Ferromanganese
Zinc smelting has historically been more difficult than the smelting of other metals eg 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 measures are taken to prevent itsolved yet for FeMn Blast Furnace and gas for its hot air stoves was supplied from pig iron Blast Furnace Therefore for ferromanganese making the producer should haveseveral Blast Furnaces and should chose a small one or which was in the end of its service life and made of the gas from other
