Have you ever wondered how aluminium is made?

Aluminium is at the heart of modern life, from the smartphone in your hand, to the plane you fly in, to the buildings where you live and work. As economies grow and living standards rise, industry experts expect that demand for aluminium will increase.

Step 1: Bauxite Mining
The production process for aluminium starts with the mining of bauxite ore. Layers of bauxite are generally found near the surface so it is extracted through open cast mining. Around 90% of the world's resources are in tropical & sub-tropical regions
Step 2: Alumina Refining
Bauxite is refined into alumina using the Bayer process. Two or three tonnes of bauxite are required to produice one tonne of alumina. In the digestion stage, hot caustic acid is added to the bauxite to dissolve the aluminium bearing minerals in the bauxite. Clarification separates bauxite solids from the pregnant liquor via sedimentation. In the precipitation stage, alumina crystals are recovered from the liquor via crystallization. Calcination is a roasting process to remove the remaining water.
Step 3: Aluminium Smelting
Alumina is smelted into aluminum using the Hall-Heroult process. It takes two tonnes of alumina to produce one tonne of aluminium. Alumina is poured into special reduction cells called pots with an electrolytic bath of molten salt called cryolite at temperatures around 960 degrees Celsius. An electrical current is then projected into the mixture at 400KA or above. This current then breaks the bonds between aluminium and oxygen atoms in alumina, resulting in liquid aluminum settling at the bottom of the reduction cell.
Step 4: Casting
Aluminium is then transferred to the cast house, where it is made into products using several different methods. Alloys are added into many of our products, according to customer specifications, before the solidification stage. In re-melt casting aluminum, at a temperature of 700 degree Celsius, is poured into moulds. The moulds are cooled and the aluminium solidified before being packed and shipped to the customer. EGA also supplies nearby customers in Khalifa Industrial Zone Abu Dhabi. Receiving aluminum as molten metal eliminates the need to use high energy to re-melt it before use. We transfer molten metal by truck in preheated 14.5 tonne crucibles which can keep the metal liquid for 18 hours at temperatures of around 780 degrees Celsius.

At about 5.00 the ingot caster is shown. At my plant we had electromagnetic casting molds which were fascinating to study. We also had older direct chill molds. I was told that the use of EMC eliminated the need to use a scarfing saw to prep the ingot sides prior to hot rolling. DCC would cause unwanted surface defects that the saw would remove. Nice animation.

You can just take out the aluminium. And the process just continue, you don't need to stop the reduction cell(pot) to take out the aluminium.

the video graphics, design and some chemical parts are all well made, although there are some very nasty mistakes in fundamental chemistry and process names... first, Hall-Héroult is a refining process of bauxite, and not the electrolysis process. second, What are those electrons flowing from the anode (+) to the cathode (-)? it's not a galvanic cell (e.g. battery), but the opposite (electrolytic cell) Also, from the way it's presented, it seems that carbon is a must reagent from the reaction, to take the lone Oxygen atoms away... for a better chemical explanation of this part: minute 2:05 at kzbin.info/www/bejne/hIiUnGetg6qkZ5Y from Royal Society of Chemistry. (sorry for any bad English ...)

[@quangho8120]

Isn’t electrolysis also used for the extraction of aluminium from aluminium oxide that comes from bauxite?

[@jadinwemette8251]

Didn't see that in the video leading up to the point of the reduction cells process. Only seen that alumina is fed into the cell using the electrolysis of the anodes and cathodes with the solution separating oxygen from the aluminum then created co2 that deteriorates the carbon blocks or anodes. Recycle and reuse must be a huge part of the process also.

[@esquivel1]

Please, what happens to the caustic liquid after filtration? Are there any uses for it to sell as a byproduct?

Hi, if you want to know a detailed description of the Hall Héroult process, you can go to the following link: kzbin.info/www/bejne/eX2aXnp4mLeAisU It is in Spanish language for latino students of metallurgy.

[@charlesjojobesitan5504]

() is silver-white metal, very lightweight yet relatively strong and ductile thatit can be drawn into wires or pressed into sheets or foil. The name was derived from n, the Latin name for alum (an aluminum sulfate mineral). It is the most abundant metallic element and the third most abundant of all elements in the earth’s crust, making up 8% of the crust by weight. Aluminum does not occur in the metallic state in nature because aluminum metal reacts with water and air to form powdery oxides and hydroxides.
