Why is partial roasting of sulphide ore done in metallurgy of copper?

Options:

Answer:

Solution:

Partial roasting of sulphide ore forms metal oxide.
This oxide then reduces the remaining sulphide ore into metal.
$2 C u_{2} S + 3 O_{2} \to 2 C u_{2} O + 2 S O_{2}$
$2 C u_{2} O + C u_{2} S \to 6 C u + S O_{2}$
This process is called autoreduction.
