Bauxite is an ore that was first discovered in 1822; various other types of bauxite have since been found and they all contain about 50 % alumina. They are virtually the only type of ore used to extract aluminium. Bauxites are aluminium-rich products derived from the weathering of lime and silicate gangue. They are found in those regions where in

Bayer process

In the first stage of the extraction process, bauxite is processed to aluminium oxide (or alumina as it is also called). By far the most important, and in the western world only, process for producing aluminium oxide is the Bayer process, which was initially developed before 1900 and has subsequently been improved and refined considerably. (A

Bonding - a versatile joining technology for aluminium

Bonding – a joining technology gaining ground In the New Stone Age people used molten tree resin to bond their arrow heads and axe heads to the shaft. Almost 10,000 years ago they were using an adhesive to join things together, thus making bonding one of the oldest human technologies. Today bonding is a proven joining technology, alongside welding
