No. All of the aluminum been used today comes from a different ore Bauxite, that is a combination of several metal oxides like iron oxide that gives the red orange color that characterize this mineral when found in nature. By the way, it is one o

Note that in some cases ore value (given below) and metal value are not the same (Bismuth, Iron ores). Alloys, too, often have a higher value than the ores/metals they are made of. In most cases furniture made from the ore is as valuable as furniture made from a pure (non alloy) metal, while requiring significantly less processing.

Alunite in El Gideda iron mine, Bahria Oasis, occurs as very soft and light white to pinkish beds and pockets ranging in thickness from few cm to 0.5 m intercalated with glauconit
and Fe. The former three elements form alunite and halloysite. Iron forms at least a part of the iron ore in the El Gideda mine. Glauconite intercalated by alunite is highly destabilized with fractured pellets and iron rims as well as low potassium content. Therefore, alunite and halloysite can be considered as by
Aluminum processing Aluminum processing Ores Aluminum is the third most abundant element on Earths surface. Only oxygen and silicon are more common. Earths crust to a depth of 16 km (10 miles) contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.
The Earth Science Alunite Deposit was closed at the time of data entry with no known plans to re open. Production size when active was considered to be small. The ore mined is composed of alunite. The ore body takes a blanket shape 4,876 meters (16,000 feet) long, 3,048 meters (10,000 feet) wide, and 304 meters (1,000 feet) thick.
Bauxite is the principal ore of aluminum. The first step in producing aluminum is to crush the bauxite and purify it using the Bayer Process. In the Bayer Process, the bauxite is washed in a hot solution of sodium hydroxide, which leaches aluminum from the bauxite.

Common member of the alunite supergroup. The Al analogue of jarosite and the K analogue of natroalunite. Alunite has been used for dating (K Ar method) of weathering processes in ore deposits or of the deposition of alunite in caves.

Alunite is an analog of Jarosite, where aluminium replaces Fe 3+. Alunite occurs as a secondary mineral on iron sulfate ores. Alunite occurs as veins and replacement masses in trachyte, rhyolite, and similar potassium rich volcanic rocks.
