Formation  of metallic copper from the sulphide ore in the commercial thermo metallurgical process essentially involves which one of the following reactions as major reaction.

Consi der the following metallurgical processes

$(I)$ Heating impure metal with $CO$ and distilling the resulting volatile carbonyl (b.p. $43\,^oC$ ) and finally decomposition at $150^o-200\,^oC$ to get the pure metal

$(II)$ Heating the sulphide ore in air until a part is converted to oxide and then further heating in the absence of air to let the oxide react with unchanged metal sulphide

$(III)$ Electrolysis of the molten electrolyte containing approximately equal amounts of the metal chloride and $NaCl$ to obtained the metal

The processes used for obtaining magnesium, nickel and copper are respectively

The element that can be refined by distillation is :

Sulphide ion is soft base and its ores are common for metals.

$(a)$ ${Pb}$      $(b)$ ${Al}$     $(c)$ ${Ag}$     $(d)$ ${Mg}$
