Extraction for zinc from zinc blende is achieved by

A.electrolytic reduction

B.roasting followed by reduction with carbon✓ Correct

C.roasting followed by reduction with another metal

D.roasting followed by self-reduction

Explanation

The zinc blende is first subjected to roasting. The reaction is given below: 2 2 2ZnS+3O 2ZnO+2SO -> Now, this zinc oxide is reduced with carbon. The reaction is given below: 1270 ZnO+C Zn+CO K -> So the zinc is obtained.
