A) roasting followed by self-reduction
B) electrolytic reduction
C) roasting followed by reduction with carbon
D) roasting followed by reduction with another metal
Correct Answer: C
Solution :
[c] Extraction of Zn from zinc blends is achieved by roasting followed by reduction with carbon. Reactions involved are: \[2ZnS+3{{O}_{2}}\xrightarrow{heat}2ZnO+2S{{O}_{2}}\left( Roasting \right)\] \[ZnO+C\left( Coke \right)\xrightarrow{heat}Zn+CO\left( Reduction \right)\]You need to login to perform this action.
