Smelting is a metallurgical process in which ores are melted in a specially designed furnace in order to extract metals from the ores. Techniques vary, depending on the metal and the ore, but some common principles apply. ore is generally processed before smelting in order to remove gangue (the unwanted rock or mineral aggregates that are mined along with the ore). After processing, the resulting ore concentrate is smelted. During smelting, ore is reduced—that is, oxygen is removed from metal oxides to yield the metal—and impurities are separated from the metal. Additives placed in the smelting furnace along with the ore help the metal to melt and physically separate from the impurities.
