Reduction of Metals (Extraction from Ore) - A .

Reduction 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.

Extraction of Crude Metal from Concentrated Ore .

After concentration of ores, we must now extract metal from in it. This step will give us metal in its pure form i.e. the native form of metal. First, we must convert the ore to a suitable form. The metals need to be in an oxide form for the reduction process to be easier. Hence the ores are converted to oxides, so it is ideal for reduction.
