Bauxite is mainly composed of alumina, silica, iron oxide and titanium dioxide. Around 70% of bauxite ore in the world adopts Bayer process to produce alumina. Then by Hall-Héroult electronic process, alumina can be reduced to pure aluminum. Bayer process steps for alumina production
Vibrating hand tools are not an important part of the process at bauxite mines, but are common at alumina refineries. Nevertheless, most bauxite mines and alumina refineries are located in tropical climates, so cold-provoked vasospasm is less likely. Bauxite is a low-level naturally occurring radioactive material.
