Answer:
Metals such as iron, zinc, lead, copper, etc., are in the middle of the reactivity series. These are moderately reactive metals and are usually present as sulphides or carbonates.
Explanation:
The moderately reactive metals are extracted by the reduction of their oxides with carbon, aluminium, sodium or calcium. 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.
