    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, 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 it The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphale
