Can Aluminium be extracted from clay?
It is not bauxite or something else i am asking my teacher told that sand and clay particles have aluminum in it but is is not yet known how to extract it
Why was gold discovered and used before aluminium?
Gold is found in the elemental state as it is quite nonreactive -- hence it can be "panned" as in the old westerns. Gold was known from the earliest times. Aluminium is always present combined in an ore and is quite difficult to extract and refine.
What is Aluminum obtained commercially from?
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− See the related link for more information.
Why scientists in 1800 could not extract aluminium from alumina?
The necessary technological conditions did not exist.
How do you extract aluminium from Aluminium Oxide?

Why was aluminium more expensive in the 1850s?
Aluminium is a reactive metal and so is hard to extract from it's compounds without modern technology.
Why is aluminum easier to extract then gold?
It is not. Gold is easier. Aluminium is energy intensive.

Why do scientists extract DNA?
Scientists might extract DNA for many reasons. In a homicide case, or a case in which an unidentified body has been found, scientists extract DNA from the bones (if only bones are found) to identify Null. To check for birth defects in humans or animals. *In an unidentified creature, scientists will want to check all deails *etc.
Origin Name For Aluminum?
The name "aluminum" originates from the mineral alum, in which the compound was initially found. The term was later modified to "aluminium" based on the naming conventions of other elements, and eventually simplified to "aluminum" in the United States.
How has a change in the method of extraction for aluminium caused the metal to decrease in value?
it has made it cheaper to extract and it is a quicker and simpler proses
Have scientists discovered the method that plants use to extract hydrogen from water?
yep
Why does Australia extract aluminium?
Aluminium is a major industrial metal, and is refined from bauxite. Some of the refining is done in Australia, and some is refined in New Zealand at Te Wai Point at the south of NZs South Island.

Suggest why aluminium is more expensive than iron?
Aluminium is more expensive than iron because of its lower abundance in the Earth's crust. It is also more costly to extract and refine aluminium due to the energy-intensive process of electrolysis. Additionally, aluminium has a higher demand and is used in a wide range of industries which further contributes to its higher price.
