aluminium electrolysis

Step 2 aluminium electrolysis:

Aluminium ions go to the anode to gain electrons

Anodes are recycled into new ones every month or so beacuse

Oxygen atoms from metal oxides bond with the carbon and carry it away (Co2)

Step 3 aluminium electrolysis:

Oxygen ions lose electrons to the cathode.

Step 1 aluminium electrolysis:

Aluminium oxide should be melted or dissolved so that electricity can pass through it

Step 4 aluminium electrolysis:

Liquid pure aluminium sinks to the bottom due to higher density

Step 5 aluminium electrolysis:

Pure aluminium is harvested through a tap at the bottom of the container, with no need to stop or restart the process.,

Alumina

Aluminium oxide after being purified and separated from rocks in Ore.

Aluminium electrolysis requires

An extreme amount of energy and electricity and would be costly to stop and restart.

Aluminium electrolysis produces __ of aluminium in 1 hour

50kg

Aluminium Ore (aluminium oxide - Al²O³) is called

Bauxite

Aluminium can be extracted through alumina through

Electrolysis.

Choose of aluminium extraction site should be close to a powerstation So:

energy can be easily transported

Choice of extraction sight should be close to a coast so:

Raw materials can be easily imported

Choice of aluminium extraction site should be near a town so

Workers have a place to live

Choice of extraction sights should be away from bust areas to

Avoid poluting local towns.

Cryolite

a molten substance that alumina is dissolved in to lower the melting point of the substance, saving energy

Electrolysis is a

Constant process
