By which process P b and S n are extracted respectively?
Options
- ACarbon reduction – self reduction
- BSelf reduction – carbon reduction
- CElectrolytic reduction – cyanide process
- DCyanide process – electrolytic reduction
Correct answer
B. Self reduction – carbon reduction
Step-by-step solution
P b S + 2 P b O → 3 P b + S O 2 ( s e l f r e d u c t i o n ) S n O + C → S n + C O ( C a r b o n r e d u c t i o n )
