The methods chiefly used for the extraction of lead and tin from their ores are respective
A.self-reduction and carbon reduction✓ Correct
B.self-reduction and electrolytic reduction
C.carbon reduction and self-reduction
D.cyanide process and carbon reduction
Explanation
The extraction of lead is done by self-reduction. The reaction is given below 2 2 2PbS+3O 2PbO+2SO → 2 4 PbS+2O PbSO → 2 2PbO+PbS 3Pb+SO → 4 2 PbSO +PbS 2Pb+2SO → The extraction of tin is done by carbon reduction. The reaction is given below: 2 SnO +2C Sn+2CO →
