TOPIC EIGHT EXTRACTION OF METALS CHEMISTRY
To extract the metal, oxygen must be removed from it. This reaction if called reduction. Because the metal is always the most electropositive part of an ore, and so has a positive oxidation state, the formation of the free metal from its ore is always a reduction. M n+ + ne- →M o. Very reactive metals like sodium and potassium are strongly bonded in their ores. The more reactive the metal is
