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
Answer :
roasting followed by reduction with carbon
Solution :
NOTE : Extraction of $$Zn$$ from $$ZnS$$ (Zinc blende) is achieved by roasting followed by reduction with carbon.
$$2ZnS + 3{O_2} \to 2ZnO + 2S{O_2}$$
$$ZnO + C \to Zn + CO$$
