extracting metals using electrolysis

Types of Extraction S cool, the revision website

When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to extract from its compound. Electrolysis Electrolysis is the most powerful extraction method.

inorganic chemistry Extraction of metals using

I was thinking that highly electropositive metals like Na+, Li+ and others which have highly negative reduction potentials should be difficult to reduce as hydrogen would be preferentially reduced. For example, in electrolysis of NaCl, Na+ is left in the solution as NaOH while it is hydrogen that is reduced.
