Describe with one example, how moderately reactive metals (which are in the middle of reactivity series) are extracted.
The extraction of moderately reactive metals (which are in the middle of reactivity series) is done by the process of reduction of their oxides with carbon, aluminium, sodium or calcium.

For example:- When Zinc sulphide (zinc blende ore) is strongly heated in air (roasted), it forms zinc oxide and sulphur dioxide. This process is called roasting. Then, zinc oxide is heated with carbon to form zinc metal. This process is termed as reduction.
