Question

how to extract medium reactive metal​

Answer 1

$\huge\mathbb\green{HELLO!!!}$

Metals of medium reactivity level. Metals in the middle of the reactivity series i.e metals like lead, zinc, copper, etc are moderately reactive and are generally present as carbonates or sulphides. Sulphides ores are converted into oxides by heating strongly in the presence of excess air.

Answer 2

By the way your subject is wrong

But still I am telling you

The extraction method used depends upon the metal's position in the reactivity series . ...

If a metal is less reactive than carbon, it can be extracted from its compounds by heating with carbon. ...

Copper oxide is reduced as carbon is oxidised , so this is an example of a redox reaction.
