Bauxite grinding typically has specific process conditions, such as high temperature and an alkaline medium which significantly alter bauxite grindability. Safonov et al. [3] developed a study to evaluate the effects of process parameters on grindability and BWI considering two types of bauxite as a function of composition: gibbsite and diaspore.

Bauxite (Al 2 O 3) is called aluminium ore. The bauxite is purified to yield a white powder from which aluminium can be extracted-aluminium oxide (also known as alumina). By the Bayer Process, the bauxite is purified. The ore is first combined with a hot, condensed sodium hydroxide solution.
