Q. The methods chiefly used for the extraction of lead and tin from their ores are respectively

The d-and f-Block Elements

Solution:

The methods chiefly used for the extraction of lead and tin from their ores are respectively self reduction and carbon reduction. (Because the process of heating the ore strongly in the presence of excess of air is called roasting. It is mainly used in case of sulphide ores and the process of extracting a metal by fusion of the oxide ore with carbon is known as smelting.)
