Smelting is the general term for getting a metal from its natural ore. Gold is an exception, because it is usually found as a pure metal. Other metals, like iron, copper, zinc, and silver, need to be got from their ore. The process of smelting always involves heating the ore, and may also use a reducing agent like coke or charcoal.
