Self-reduction of `Cu_(2)S` to `Cu` can be carried out in.

A

Bessemer converter

B

blast furnace

C

both `(a)` and `(b)`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
Matte is obtained in blast furnace and that contains mostly `Cu_(2)S` and `FeS`. It is transferred to Bessemer converter where self-reduction takes place according to the following reactions.
`2Cu_(2)S + 3O_(2) rarr 2Cu_(2)O +2SO_(2)`,
`2Cu_(2) +Cu_(2)S rarr 6Cu+SO2`.

    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. In self-reduction, the reducing species is.

    Consider the following four electrodes: A=Cu^(2+)(0.0001M)//Cu_((s)) B=Cu^(2+)(0.1M)//Cu_((s)) C= Cu^(2+)(0.01M)//Cu_((s)) D=Cu^(2+)(0.001M)//Cu_((s)) If the standard reduction potential of Cu^(+2)//Cu is +0.34V , the reduction potentials (in volts) of the above electrodes follow the order
