Used aluminum is not a waste, it is a raw material, a wealth to exploit CHARACTERISTICS The invention of the aluminum alumina electrolysis process by Hall and Héroult dates back to 1886 In Canada, aluminum is one hundred years old and it still has interesting properties for several fields of application: Resistance to corrosion in several media
How aluminum is made - material, manufacture, making, used ,
Raw Materials Aluminum compounds occur in all types of clay, but the ore that is most useful for producing pure aluminum is bauxite Bauxite consists of 45-60% aluminum oxide, along with various impurities such as sand, iron, and other metals
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
This makes aluminium an excellent building material - reshaped and repurposed to meet the needs and challenges of different times and products How it’s made 1 Bauxite mining Aluminium production starts with the raw material bauxite, which contains 15-25 percent aluminium and is mostly found in a belt around the equator
The corrosion data in this section is mainly based on the results of general corrosion laboratory tests, which are not strictly comparable with actual service conditionsThe corrosion tables provide an initial guide to the selection of materials and are intended to facilitate understanding of the different types of corrosion damage that can arise due to poor material selection
