Aluminum Smelting Furnaces and Processing of

The smelting of aluminum begins with the extraction of bauxite ore by a form of open cast mining. The bauxite is washed and screened before being converted to alumina, a white powdery element from which the aluminum is produced. Aluminum smelting is carried out in a Hall Heroult reduction cell, which is lined with carbon. A mix of alumina and cryolite is fed into the cell and carbon blocks

Radiological Assessment for Bauxite Mining

Potential radiological impacts from mining and processing are mainly due to the radiation associated with radionuclides 232 Th and 238 U and their decay products, and there is a relatively small, essentially negligible, contribution to radiation dose estimates from 40 K in the bauxite. The approximate K chemical concentration of 0.2 wt % in bauxite ore corresponds to a K-40 activity of 0.062
