(i) Self reduction , (ii) Carbon reduction , (iii) Metal displacement method , (iv) electrolytic reduction ,(v) Carbon monoxide reduction, (vi) Hydrogen reduction

Filo · Accepted Answer

Following three processes are employed for the extraction of lead from ore galena.
(i) Self reduction , (ii) Carbon reduction , (iii)Carbon monoxide reduction.
(i) Self reduction

P b S + 1/2 O_{2} ⟶ P b O + S O_{2} ↑

P b S + 2 P b O ⟶ 3 P b (l) + S O_{2} ↑

(ii) Carbon reduction

P b O + C ⟶ P b (l) + C O_{2} ↑

(iii)Carbon monoxide reduction.

P b O + CO ⟶ P b (l) + C O_{2} ↑
