  • Reduction of Metals (Extraction from Ore)A-Level Chemistry

    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. This is the method used to extract titanium.
