Question

Why iron is extracted by reduction using carbon but not aluminium???

Answer 1

Answer:

We can see from the table that reactive metals, such as aluminium, are extracted by electrolysis , while a less reactive metal, such as iron, may be extracted by reduction with carbon. Because gold it is so unreactive, it is found as the native metal and not as a compound.

Explanation:

It does not need to be chemically separated. However, chemical reactions may be needed to remove other elements that might contaminate the metal.
