May 08, 2014· Handarm 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 coldprovoked vasospasm is less likely.
A simplified process flow diagram of the Bayer process used at the Wagerup refinery is presented in Figure 6. Bauxite Grinding and Slurry Storage Bauxite is ground to less than mm particle size at the refinery, using semiautogenous grinding mills (SAG and/or Ball mills) to ensure sufficient solidliquid contact during the

Red mud, or bauxite residue, is a sideproduct of the Bayer process, the principal means of refining bauxite en route to alumina. The resulting alumina is the raw material for producing aluminium by the Hall–Héroult process. A typical bauxite plant produces one to two times as much red mud as alumina.
