Answer

Both A and R are true but R is not the correct explanation of A.

Explanation — Metallurgy deals with the production and purification of metals and manufacture of alloys. Hence, assertion (A) is true.
They are many different methods of concentration or purification of an ore and reduction is one of the methods of extraction of metals. Hence, reason (R) is true.

But reason (R) doesn't explain why it is important to purify and produce the pure metal from the process of metallurgy. Hence, reason (R) is not correct explanation of assertion (A).
