types of mining for bauxite in sweden

Bauxite Sandatlas

Bauxite deposits form close to the surface. Hence, all the mines in the world are open pit. About 8-14 tons of bauxite is needed to produce one ton of aluminum 1. So the ore of aluminum needs to be fairly rich in this metal to be worth mining. Aluminum is extracted solely from bauxite, but that does not mean that there are no alternatives.

Aluminium mineral extraction– open pit, surface mining

Bauxite is the only ore containing 20-25 percent of aluminium from where the metal is extracted and commercially produced. The open pit or surface mining process is carried in this case since bauxite is mostly found near surface areas where the layers of soil contain a mixed amount of various minerals, iron oxides and titanium dioxide.

Bauxite Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH)) and small
