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.
