Extraction of Metals
Metals can be extracted by physical method:
1. Heating the metal ore alone (for stable metals)
2. Heating the metal ore with carbon (for reactive metals)
3. Electrolysis of the molten ore (for very reactive metals)
Examples
Reactivities of Metals
A more reactive metal:
1. requires a lower temperature to start the reaction
2. reacts faster
3. gives out more heat during a reaction
