Pure iron corrodes ...What Is a Smelter?, · 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 ...What Is a Smelter?, · Smelting is a process by which pure metals like copper, silver and gold are extracted from ore that is mined from the earth. People started smelting more than 1,000 years ago.
