medium
The extraction of zinc from zinc blende is achieved by
A
electrolytic reduction
B
roasting followed by reduction with carbon
C
roasting followed by reduction with another metal
D
roasting followed by self-reduction
Solution
The extraction of zinc from zinc blende is carried out by first roasting and then reduction with Carbon.
Roasting:
$2 ZnS +3 O _2 \rightarrow 2 ZnO +2 SO _2:$
Reduction with Carbon:
$ZnO + C \stackrel{>\,1270\, k }{\longrightarrow} Zn + CO$
