Question

Give a reason for the following:

Carbonate and sulphide ores are usually converted into oxides during the process of extraction of metals.

Give reasons:

Metal sulphides and carbonates should be converted to their metal oxides in the process of extraction of metals.

Answer 1

It is easier to extract metals from their oxide ores by reduction process than from their carbonate and sulphide ores. Hence, carbonate and sulphide ores are usually converted into oxides during the metals extraction process.
