medium
Extraction of zinc from zinc blende is achieved by
A
roasting followed by self-reduction
B
electrolytic reduction
C
roasting followed by reduction with carbon
D
roasting followed by reduction with another metal
(AIEEE-2012)
Solution
Extraction of $Zn$ from zinc blends is achieved by roasting followed by reduction with carbon. Reactions involved are
$2ZnS + 3{O_2}\xrightarrow{{heat}}2ZnO + 2S{O_2}\,({\text{(Roasting}})$
$ZnO + C\,(Coke)\xrightarrow{{heat}}Zn + CO\,{\text{(Reduction}})$
