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 :
Extraction of Zn from zinc blends is achieved by roasting followed by reduction with carbon. Reactions involved are : \[2ZnS+3{{O}_{2}}\xrightarrow[{}]{heat}2ZnO+2S{{O}_{2}}\](Roasting) \[ZnO+C(Coke)\xrightarrow[{}]{heat}Zn+CO\](Reduction)You need to login to perform this action.
