Smelting is the general term for getting a metal from its natural oreGold 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 charcoalMost ores are oxides sulfides or carbonates
