(S) | Calcination |
Options:
Answer:
B
Solution:
(P) ZnO → Zn (Self reduction) incorrect (ZnO is reduced by C/CO, not self-reduction)
(Q) Cu (impure) → Cu (pure) (Electrorefining) Correct
(R) Pig iron → Wrought iron (Oxidation of impurities) Correct
(S) PbS → PbO (Calcination) Incorrect (PbS undergoes roasting, not calcination)
