Techniques For Metal Extraction
The following table shows how the method for the extraction of a metal depends on its position in the reactivity series.
The following video explains why it is necessary to use different techniques to extract iron from its ore and aluminium from its ore.
1. Describe what an ore is.
Ore is a compound that contains a metal. Ores are in limited supply.
2. Explain what happens during oxidation and reduction reactions.
Oxidation is gaining an oxygen - how ores are form.
Reduction is losing an oxygen - how metals are extracted from their ore.
3. Explain how our method of extracting metals depends on their reactivity.
