Zinc - History | Britannica

Zinc - Zinc - History: Metallic zinc appeared much later in history than the other common metals. Copper, lead, tin, and iron can be obtained as the molten metals by heating their oxide ores with charcoal (carbon), a process called reduction, in shaft furnaces, which were developed quite early in history. Zinc oxide, however, cannot be reduced by carbon until temperatures are reached well ...
