Bauxite Mining and Alumina Refining: Process Description

May 08, 2014· Hand-arm vibration syndrome seems to be rare in bauxite mining and alumina refining. 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.
