Question

Give reasons.

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

Give a reason for the following:
Carbonate and sulphide ores are usually converted into oxides during the process of extraction of metals.

Answer 1

Carbonate and sulphide ores are usually converted into oxides during the process of extraction because metals can be easily extracted from their oxides rather than from their carbonates and sulphides.

Answer 2

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.
