Solution

A metal carbonate reacts with a dilute acid to form $C O_{2}$ . Therefore this ore is a carbonate ore. Carbonate ore is converted into free metal in the following two steps:
(i) Calcination: The carbonate ore is strongly heated in the absence of air to get the metal oxide.
$Metal carbonate C a l c i n a t i o n - ------ \to Metal oxide + C O_{2}$
(ii) Reduction: Metal oxide is reduced with carbon to get free metal.
$Metal oxide + Carbon (coke) r e d u c t i o n - ---- \to M e t a l + C O$
