Copper is the most moble of first row transition meals and occurs in small deposits in several countries ares of copper include chalcanthite `(CuSO_(4)5H_(2)O)`, afecamie `(CuCHOH)_(3))`, cuprite`(Cu_(2)O)` Copper glance `(Cu_(2)S)` and rolachite `(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 chalopyrite in polves partial roasting, removal of Iron self-reduction.

A

FeO

B

`FeS`

C

`Fe_(2)O_(3)`

D

`FeSiO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
Iron is removed from chalcopyrites `(CuFeS_(2))` as slag `FeSiO_(3), FeO+SiO_(2) to FeSiO_(3)`

i) Bauxite ( Al_2O_3 * 2H_2O ) ii) Copper iron pyrites ( CuFeS_2 ) iii) Gypsum ( CaSO_4 * 2H_2O ) Which of the given ores contains two metals ?

A composite bar of uniform cross-section is made of 25 cm of copper, 10 cm of nickel and 15 cm of aluminium with perfect thermal contacts. The free copper end of the rod is at 100^(@)C and the free aluminium ends is at 0^(@)C . If K_(Cu)=2K_(Al)" and "K_(Al)=3K_(Ni) , then the temperatures of Cu-Ni and Ni-Al junctions are respectively. (Assume no loss of heat occurs from the sides of the rod, K-thermal conductivity).
