Iron, Copper and Aluminium

1
Iron, Copper and Aluminium

• Chemistry revision

2
In this lesson you will re-visit

• The Reactivity Series and why copper, aluminium
  and iron are extracted from their ores the way
  they are.
• What processes are used to extract the metals
  from their ores.

3
You need to be able to

• Rank metals in the Reactivity Series.
• State the reason why Carbon is important in the
  Reactivity series.
• State how a metal will be extracted given its
  position in the Reactivity Series.

• Label the equipment used to extract iron,
  aluminium and copper.
• Be able to write the equations (word and formula)
  for these reactions.
• Explain reduction and oxidation in terms of
  electron loss and gain (OILRIG).

4
The Reactivity Series
Carbon is not a metal so why is it included in
this series?
5
Iron - The Blast Furnace
This site has an animated diagram and the
equations! Make sure Boardworks is loaded.
Boardworks-The Blast furnace
Iron ore requires a two part process oxidation
and then reduction. Make sure you can label this
diagram and write out the equations.

6
Copper reduction and electrolysis
Boardworks the extraction copper
Copper should only need to be extracted with
carbon. So why is electrolysis necessary?
7
Aluminium the Hall Heroult electrolysis cell
Boardworks Aluminium extraction
Aluminium cannot be extracted by carbon at all.
This process uses HUGE amounts of electricity.
Think about environmental implications.
8
So can you?
Name the correct order of metals in the
Reactivity Series? Label the extraction processes
for iron, copper and aluminium. Write out the
word and symbol equations for each of the
processes? Discuss the environmental implications
of metal extraction processes?
