Chapter 2. Production and Processing of Aluminum
Aluminum comprises approximately 8% of the earth''s crust, making it second only to silicon (27.7%). Iron is third at about 5%. Metallic aluminum is not found in nature; it occurs in the form of hydrated oxides or silicates (clays). The principal ore from which aluminum is extracted is called bauxite after the town of Les Baux in southern France

Extraction of Metals. History ().. After the Bronze Age came the Iron Age. People discovered that a high temperature coal fire could be used for the extraction of iron from iron ore. The extraction of iron today is done in a blast furnace.. The Iron Age began in Asia and Africa in 1,100 B.C. and came to Britain in 500 B.C. In many ways, we are still in the Iron Age - take a look around.
Extraction of iron and aluminium!?
Al 3+ + 3e - --> Al. Anode: 2O 2- --> O 2 + 2e -. Whereas iron can be extracted from it''s ore haematite by reduction with carbon and heat. 2Fe 2 CO 3 + 3C --> 2Fe + 3CO 2. Therefore aluminium took longer to extract because electricity needed to be invented and a way of dissolving Al 2 O 3 before the extraction …
Iron (/ ˈ aɪ ər n /) is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth''s outer and inner core is the fourth most common element in the ...
