Which element is used to reduce metal oxides and make pure metals?

Can vary. Carbon is used quite commonly, and extracts metal oxides, works with zinc, iron, tin, lead and copper.

Final answer: Magnesium and aluminum are important reducing agents used in the production of pure metals from their oxides. Explanation: Magnesium is used to reduce metal oxides and make pure metals. For example, it can be used to reduce metal oxides like copper oxide to obtain pure copper. Chemical reduction is a common method where reducing agents like magnesium are used to isolate metals from their oxides. Aluminum is also a good reducing agent in the isolation of certain metals from their oxides.
