Solution

The correct option is B
Roasting

Roasting is done for converting sulphide metal ore to its oxide. The given ore contains sulphide. Hence, roasting is done.

Calcination is done for converting carbonate metal ore to its oxide.

Froth floatation is done for purification of sulphide ore, not for converting to its oxide.

Magnetic separation is done for purification of ore having magnetic ore and non-magnetic impurities or vice-versa.
