Extraction of zinc from zinc blende is achieved by

Options

A. roasting followed by self-reduction.
B. electrolytic reduction.
C. roasting followed by reduction with carbon.
D. roasting followed by reduction with another metal.

Answer

C

Explanation

Extraction of Zn from zinc blends is achieved by roasting followed by reduction with carbon reactions involved are :
` 2zn S + 3O_2 overset("heat") to 2ZnO + 2SO_2 ` ( Roasting )
` Zn O +C ( " coke ") underset( "heat") to Zn +CO ` ( reduction )
