Alumin(i)um is mined principally as the ore bauxite. It is processed at smelters with high electrical current. For this reason, aluminum smelters are usually located near hydroelectric plants, such as in Quebec, Canada, where hydroelectric power is abundant.
Aluminium forms very strong chemical bonds with oxygen which makes it more difficult to extract from ore than most metals. It is not possible to reduce it with carbon. Another problem is the high melting point of most of its ores - principally bauxite. For example, direct reduction with carbon, as is used to produce iron, is not chemically possible because aluminium is a stronger reducing agent than carbon.
The Hall-Héroult process, is thus used and is the major industrial process for aluminium extraction. Molten cryolite is first used to dissolve alumina and along with calcium fluoride is then electrolytically reduced to aluminium. Cryolite is Na3AlF6
Both of the electrodes used in the electrolysis of aluminium oxide are made from carbon. The cathodic reaction is Al3+ + 3e− ------> Al
The aluminium metal then sinks to the bottom of the cell and is tapped off and cast into large blocks called billets. These may be processed further as necessary.
At the anode, oxygen is formed 2O 2− ------> O2 + 4e−

Aluminum is commercially obtained from bauxite ore through a process called the Bayer process. Bauxite is first processed into alumina (aluminum oxide), which is then reduced through electrolysis to produce pure aluminum metal.

Aluminum is normally obtained by the electrolysis of its fused salts, such as aluminum oxide (Al2O3) dissolved in molten cryolite.
About 74.4 metric tons of aluminum can be obtained from the electrolysis of 175 metric tons of aluminum chloride nonohydrate.
1,075 moles of aluminium chloride are obtained.
To calculate the mass of aluminum obtained at the cathode, you first need to calculate the total charge passed through the circuit (Q = I * t). Then, using the Faraday's constant (1 F = 96,485 C/mol), you can determine the amount of aluminum produced based on the electrolysis reaction. Finally, use the molar mass of aluminum to convert moles to grams.
Mica is a mineral composed mainly of silicon, oxygen, and aluminum. It does not contain any metal that is directly obtained from it. However, mica can have trace amounts of minerals like iron, magnesium, or lithium, which are metals but not extracted solely from mica on a large scale.
Benzene is mainly produced from petroleum refining processes, particularly through the catalytic reforming of naphtha, a liquid mixture derived from crude oil. It can also be obtained as a byproduct of coal tar or produced synthetically through processes like toluene hydrogenation or dealkylation. These methods allow for the large-scale commercial production of benzene for various industrial applications.

The metal obtained from bauxite is aluminum. Aluminum is used in a wide range of applications, including construction, transportation, packaging, and electrical wiring, due to its light weight, high strength, and resistance to corrosion.
