Bauxite where is it mined

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. Other raw materials are mined as aluminium ore, but their use is minor compared with bauxite. The only significant bauxite deposits in Victoria are in South Gippsland. More than forty bauxite occurrences are known in the area. Most of the bauxite is overlain by clay, sand and gravel.

The bauxite from these sites has been used mainly as an additive to increase the alumina content of cement. There are also minor deposits of bauxite at Gelliondale and on the Mornington Peninsula.

The Aluminum Advantage. Aluminum Advantage. Product Markets. Members Area. Home » Industries » Production » Bauxite. Buyer's Guide. Bauxite ore, refined through two processes, is the primary source of aluminum. Land conservation is a key industry focus An average of 80 percent of the land mined for bauxite is returned to its native ecosystem.

Topsoil from the mining site is stored so it can be replaced during the rehabilitation process. Reserves will last for centuries Although demand for aluminum is increasing rapidly, bauxite reserves, currently estimated at 40 to 75 billion metric tons, are projected to last for centuries.

Guinea and Australia have the two largest proven reserves. A wealth of bauxite reserves Vietnam may hold a wealth of bauxite.

The West African country produced and exported 64 million metric tonnes of the ore in , which was quite a significant rise from its export volume of 56 Mt. It has the largest bauxite reserve count in the world at 40 billion tonnes. The Sangaredi mine in the Boke region is its biggest bauxite producer. Brazil, which produced 30 million metric tonnes of bauxite in , comes in fourth on the list of top-producing countries. Its output of the ore was 27 Mt in MRN is one of the two sources that supply the Hydro Alunorte refinery.

From there, the bauxite is pumped through a km long pipeline that helps reduce the industrial impact on the environment. India ranks fifth on the list of top bauxite producers, with a reported production of 26 million metric tonnes in NS Energy is using cookies We use them to give you the best experience.
