Question

Copper matte contains

• A. $CuO , FeS$
• B. $Cu _{2} S , FeS$
• C. $CuO , Cu _{2} S$
• D. $Cu _{2} S, FeO$

Answer 1

Answer: (B)

Copper matte contains $Cu _{2} S$ and $FeS$. It is produced in reverberatory furnace in the presence of air as follows

$\underset{\text { Copper pyrites(one) }}{2 Cu FeS _{2}+ O _{2}} \longrightarrow \underbrace{ Cu _{2} S +2 FeS }_{\text {Matter }}+ SO _{2}( g )$
