In the extraction of copper from sulphide ore the metal is formed by reduction of Cu_2O with

Answer»

`FeS`
`CO`
`Cu_2S`
`SO_2`

Solution :Iron has greater affinity for oxygen than COPPER.
`Cu_2O+ FeS to FEO + Cu_2S`
`FeO + SiO_2 to underset(("slag"))(FeSiO_3)`
`2Cu_2S + 3O_2 to 2Cu_2O + 2SO_2`
`2Cu_2O + Cu_2S underset("reduction")overset("auto")(RARR)6Cu + SO_2`
