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 oxide (ZnO) is the most widely used zinc compound and can be produced according to a number of different processes. In the French (indirect) method, zinc oxide is produced by the combustion of zinc metal. When zinc oxide is extracted from zinc ore or smelter by products (e.g., using oxidized zinc) it is called the American or the direct
