  • 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 ...

    However, any iron sulfide present in the ore will be converted to iron(III) oxide, which reacts with zinc oxide to form zinc ferrite: In the simple leaching process, this zinc cannot be easily recovered and so ores with low iron content are preferable. The sulfur dioxide is often converted to sulfuric acid in a plant adjacent to the smelter.
