The reactivity series shows metals in order of reactivity. The reactivity of a metal is related to its tendency to form positive ions. Iron and aluminium are extracted from their ores in various ways.
Extracting Metals by Alternative Methods
and so new ways of extracting metals from low grade ores are being developed. A low grade ore has a low concentration of metal. Phytomining and bioleaching are used to extract copper from metal contaminated land and low grade ores. They avoid the more traditional method of digging, moving and disposing of large amounts of rock.

Energy needed to produce aluminum
· Bauxite is then converted into aluminum oxide, or alumina, using natural gas at plants located in the southern United States. After alumina is extracted from bauxite ore, further processing called ''smelting'' is necessary to convert it into aluminum. In this process, alumina is dissolved in a solution and a strong electric current is applied.

By SCA Community Engagement Fellow Hayden Sloan. Aluminum (or Aluminium, if you''re not from the US) is an abundant element within Earth''s surface— but getting it out of the ground is an arduous process, requiring heavy machinery to plow up acres and acres of land.Fortunately, the environmental impact of that process can be somewhat balanced out by post-mining rehabilitation, eﬃcient ...

Aluminium production & environmental impact
1 Mineral Extraction. Bauxite mining – Alumina production – Primary aluminium production – Semi-fabrication – Product manufacturing – Product use – Product Recycling. Bauxite mining. Aluminium doesn''t occur as a isolated ore (it''s too reactive with other compounds) but as one combined with other minerals, chief of which is bauxite.
Extraction of aluminium from bauxite ore | Mastering ...
The extraction of aluminium involves two steps that is, purification of bauxite by Baeyer''s process and electrolysis of alumina. 1. Purification of bauxite by Baeyer''s process In the Baeyer''s process, the bauxite ore is heated with concentrated NaOH solution under pressure (Aluminum is purified by leaching method).The alumina dissolves as sodium meta aluminate.

Extraction of Resources | Geology
Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner.. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot ...
aluminum | Uses, Properties, & Compounds | Britannica
Occurrence and history. Aluminum occurs in igneous rocks chiefly as aluminosilicates in feldspars, feldspathoids, and micas; in the soil derived from them as clay; and upon further weathering as bauxite and iron-rich laterite.Bauxite, a mixture of hydrated aluminum oxides, is the principal aluminum ore.

How Is Aluminum Extracted From Its Ore?
· Aluminum is extracted from bauxite ore by way of the Bayer process. This requires a great deal of electricity; consequently, a large amount of aluminum is processed in Iceland, which gets its electricity through geothermal energy. To extract aluminum, the bauxite ore is first crushed, then mixed with lime, hot water and soda ash.

Extraction of Aluminium
Extraction of aluminium. Aluminium is extracted from it''s ore by electrolysis. The electrolyte has to be molten ore, if a solution was used (as in the extraction of copper) hydrogen gas would be produced instead of the pure metal. The next problem lies in that aluminium ore, bauxite, has a very high melting point - over 2000 degrees Celsius!
Aluminium is the most abundant metal on Earth, but it is expensive, largely because of the amount of electricity used in the extraction process. The extraction is done by electrolysis, but first ...
Aluminum Electrolysis | MATSE 81: Materials In Today''s World
Aluminum oxide has a very high melting point over 2000 degrees Celsius, so instead of trying to melt it the aluminum oxide is dissolved in molten cryolite. Cryolite is an aluminum compound with a much lower melting point than aluminum oxide, and so using this reduces some of the costs in extracting aluminum.
Types of Extraction | S-cool, the revision website
Methods of extraction Many metals are found in the Earth''s crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to ...

Who Discovered Aluminum?
The Deville method made it possible to produce aluminum commercially, which caused the metal''s price to drop. On April 2, 1889, American inventor and engineer Charles Martin Hull would patent an even cheaper way to extract aluminum out of aluminum oxide.
Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Extraction of Metals. Extraction of Aluminium - Electrolysis Cell.. The steel container is coated with carbon and this is used as the negative electrode ().. Aluminium oxide (Al 2 O 3) is an ionic compound. When it is melted the Al 3+ and O 2-ions are free to move and conduct electricity. Electrolysis of the alumina/cryolite solution gives aluminium at the cathode and oxygen at the anode.
How aluminum is made
The difficulty of extracting aluminum from its natural compounds kept the metal rare for many years; half a century after its discovery, it was still as rare and valuable as silver. In 1886, two 22-year-old scientists independently developed a smelting process that made economical mass production of aluminum possible.
