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−

Also How many grams and what volume of fluorine (@ STP) could be liberated at the anode? Also How many hours would the electrolysis need to continue to produce 75g of aluminum with a current of 15 amperes?
What metal is obtained from mica?
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.
What compound do you break down to get aluminum?
Aluminum is typically obtained from its ore, bauxite, through a process called the Bayer process. In this process, bauxite is dissolved in hot sodium hydroxide solution, which results in the precipitation of aluminum hydroxide. The aluminum hydroxide is then calcined to produce pure aluminum oxide, also known as alumina, which can then be further processed to obtain aluminum metal.
Is beryllium obtained commercially from seawater and salt brines?
No !
What is an azolectin?
An azolectin is a mixture of phospholipids obtained commercially from soybeans.
What does commercially obtained mean?
"Commercially obtained" refers to products or services that are purchased from a business or organization for a particular use, rather than being obtained through personal or non-commercial means. These goods are typically produced or provided for the purpose of sale in the marketplace.
Element obtained commercially from sea water?
Na, Sodium
Where can you commercially obtain calcium carbonate?
most the calcium carbonate obtained from earth.
What are some elements that are obtained commercially from sea water?
Sodium, Chloride, magnesium, and bromine
How many grams of aluminum hydroxide are obtained from 17.2 grams of aluminum sulfide?
To determine the grams of aluminum hydroxide obtained from 17.2 grams of aluminum sulfide, we need to consider the stoichiometry of the reaction between aluminum sulfide and water to form aluminum hydroxide. Given the balanced chemical equation, we can calculate the molar mass of aluminum hydroxide and use it to convert the mass of aluminum sulfide to grams of aluminum hydroxide formed.

Which metal is obtained from bauxite and what is it used for?
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.
Main element obtained commercially from seawater?
salt and fossil fuels like: petrol, kerosene, diesel etc
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.
