the mining process for aluminum Introduction

Aluminium production & environmental impact
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. Bauxite is mined from open mines from locations mainly in a wide belt around the equator. Bauxite is a mixture of aluminium hydroxide, iron oxide, titanium dioxide and kaolinite. Large deposits of bauxite occur in Australia

History of aluminium - Wikipedia
Aluminium (or aluminum) metal is very rare in native form, and the process to refine it from ores is complex, so for most of human history it was unknown.However, the compound alum has been known since the 5th century BCE and was used extensively by the ancients for dyeing. During the Middle Ages, its use for dyeing made it a commodity of international commerce.

Aluminium Mining And Processing | Mining
A two-step process is executed for the production of aluminium which involves refining bauxite to obtain alumina apart from removing impurities and then smelting alumina to produce aluminum. All forms of aluminum is produced from alumina which is obtained from the Bayer's process using the Hall-Héroult electrolytic process.

How aluminium is produced
The aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium oxide is broken down into its components using electric current.

Aluminium | Geoscience Australia
Mining. Extraction of aluminium metal takes place in three main stages¿mining of bauxite ore, refining the ore to recover alumina and smelting alumina to produce aluminium. Bauxite is mined by surface methods (open-cut mining) in which the topsoil and overburden are removed by bulldozers and scrapers. The topsoil is then stored and later used for revegetating and restoring the area after

Bauxite mining Aluminium production begins with bauxite, the "aluminium ore". Most bauxite is mined in tropical areas, with around 50km 2 of new land mined each year. At the same time, a matching area of land is restored to nature. Alumina production Pure aluminium oxide, called alumina, is extracted from bauxite via a process called refining, composed of two steps: a digestion process
