Bauxite Mining

About 7 percent of the earth’s crust is aluminium, making it the third-most abundant element after oxygen and silicon. Aluminium production starts with the raw material bauxite.

Bauxite Mining Process

Bauxite is a mineral found mostly in a belt around the equator. Bauxite, containing 15-25 percent aluminium, is the only ore that is used for commercial extraction of aluminium today.

The bauxite occurs mostly in the tropics, in horizontal layers normally beneath a few meters of overburden. The layers are usually mixed with various clay minerals, iron oxides and titanium dioxide. It is the iron that gives bauxite a deep red color.

Bauxite Mining

How much bauxite is there?

Known reserves of bauxite are around 29 billion metric tons. At the current rate of extraction, these reserves will last more than 100 years.

When we include undiscovered bauxite resources, this number is estimated at 55-75 billion metric tons.
This extends the time perspective to 250-340 years.


How do we get bauxite from mines?

Bauxite is usually covered by an overburden of several meters of rock and clay, which must be removed before the bauxite can be recovered. Then, the bauxite is transported to crushing or washing plants, before it is transported for processing.

The clay is then usually deposited in tailing ponds. After its use, these tailing ponds are replanted using local species to re-establish natural vegetation.
