Formation of metallie copper from the sulphide ore in the normal thermo-metallurgical process essentially involves which one of the following reaction?

A

`CuS+(3)/(2)O_(2) to CuO+SO_(2), CuS+C to Cu+CO`

B

`CUS+(3)/(2)O_(2) to CuO +SO_(2), 2CuO+CuS to 3Cu+SO_(2)`

C

`CuS+2O_(2) to CuSO_(4), CuSO_(4) to 2Cu+2SO_(4)`

D

`Cus+(3)/(2)O_(2) to CuO+SO_(2), CuO+CO to Cu+CO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
The reaction involved in the extraction of copper ore
`(a) CuS+(3)/(2) O_(2) to CuO+SO_(2)` (Roasting)
(b) `2Cu++CuS to 3Cu+5SO_(2)` (Auto reduction)
