The roasting reaction in the metallurgy of Cu is

Answer»

`CuFeS_(2) to CuO+ Fe_(2)O_(3) +SO_(2)`
`2CuFeS_(2)+O_(2) to Cu_(2)S+2FeS+O_(2)`
`CuFeS_(2)to Cu_(2)O +Fe_(2)O_(3) +SO_(2)`
NONE of the above

SOLUTION :`2CuFeS_(2) +4O_(2) overset (5[O])to Cu_(2)S+2FeS+SO_(2)`is the ROASTING reaction in Cu metallugy .
