Bauxite is hydrated aluminum oxide, mixed with sand and a few other things.
You first crush the bauxite and put it in heated sodium hydroxide solution. This dissolves the silicon oxide and aluminum oxide; the other impurities fall to the bottom of the container and are filtered out.
Next, bubble carbon dioxide through the solution. This neutralizes it, and causes the aluminum oxide to fall out of solution. Filter it and dry the aluminum oxide.
You next need cryolite - sodium fluorite plus aluminum fluorite. Mix it with the aluminum oxide, heat it up to melting, pour it into an electrolysis pot, insert a carbon anode, and apply 5 volts at 150,000 amps - I'm not kidding, that's how much power it takes. The aluminum will sink to the bottom and flow out a hole in the bottom of the pot. When it stops flowing, you replace the anode - they don't last long - scrape out the junk, refill the pot and go back to work.
What else can I help you with?
What is the rock used to make aluminum?
The rock used to make aluminum is called bauxite. Bauxite is a sedimentary rock that is the primary source of aluminum. It is mined and processed to extract aluminum oxide, which is then used to produce aluminum metal.
What can bauxite make?
Bauxite is the primary source for aluminum production. It is refined to extract aluminum oxide, from which pure aluminum is obtained through electrolysis. Aluminum is a versatile metal used in a variety of applications, from construction to transportation.
Is bauxite corrosive?
No, barium itself is not corrosive, however, it will react readily with water to form barium hydroxide, which is rather caustic. Additionally, many barium compounds are toxic.
What is the ore from which aluminium oxide is obtained?
Aluminium oxide is typically obtained from bauxite ore through the Bayer process. Bauxite is a sedimentary rock that contains high amounts of aluminium hydroxide minerals, which are processed to extract aluminium oxide, also known as alumina.
What is a natural source of aluminum?
Bauxite ore is the primary natural source of aluminum. It is a sedimentary rock that contains a high amount of aluminum hydroxide minerals, which are processed to extract aluminum metal.
How much is it to extract bauxite?
5million pounds
How can we extract metal from bauxite ore?
Extracting aluminum from bauxite ore requires a large amount of electricity.
