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.
Iron is removed from chalcopyrite as.

A

`FeO`

B

`FeS`

C

`Fe_(2) O_(3)`

D

`FeSiO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
The partically roasted ore is mixed with silica and little coke and then is heated in a blast furance when `FeO`, which is present as impurity is removed as ferrous silicate slag.
`FeO SiO_(2) rarr FeSiO_(3) darr`.
