Smelting is widely practiced today and has a long history dating back to the Bronze Age when ancient peoples first learned the technique. See also where does energy go. What is metal separation? Metal separation is a critical process within a recycling plant.
WebbReduction of metal halides with metals. In many cases, carbon cannot be used to reduce the metal oxide to the metal as the metal reacts with carbon to form the carbide instead. It is possible to avoid this problem by first converting the ore to the chloride, and then reducing the chloride with a more reactive metal such as magnesium or sodium.
