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 This process peaked in 1960, when it accounted for 5% of world zinc production.
