Copper is the most noble of first row transition metals and occurs in small deposits in serveral countries. Ores of copper include chalcanthite `(CuSO_(4).5H_(2)O)`, atacanite `[Cu_(2)Cl(OH)_(3)]`, cuprite `(Cu_(2)O)`, copper glance `(Cu_(2)S)`, and malachite `[Cu_(2)(OH)_(2)CO_(3)]`. However, `80 %` of the world copper production comes from the ore chalcopyrite `(CuFeS_(2))`. The extraction of copper from chalcopyrite involves partial roasting, removal of iron and self-reduction.

Text Solution

Verified by Experts

The correct Answer is:
A
Partial roasting :
`2CuFeS_(2) + O_(2) overset (Delta) rarr Cu_(2)S + 2FeS + SO_(2)`
`2FeS + 3O_(2) rarr 2FeO + 2SO_(2)`.
