Question

Extraction of metals
(1) upper
(2) middle
(3) lower

Answer 1

Extraction of upper metals by electrolysis

Extraction of middle metals by calcination and roasting after that refinning

And extraction of lower merals by refinnng

Answer 2

Highly reactive: The process electrolysis is used.

Medium reactive: The process of calcination for carbonate ores and roasting for sulphide ores.

They both are then later reduced using carbon to form metal and carbon monoxide.

Less reactive: The process of roasting and later reducing is done.
