For the BR pretreatment (termed as GBR), wet grinding was carried out in a ball mill (QM-QX, Nanjing University Instrument Factory). The process parameters were set to a ball: water: BR mass ratio of 8:2:1, a revolution speed of 400 rpm, and ball grinding time of 30 min, which was referred to Kinnarinen et al. (2015).

grinding is a relatively new area and considers grinding below 30 μm down to around 10 μm. Below 10 μm, the term "very fine or ultrafine grinding" can be used. The energy consumption in ball milling rises sharply for grinding products below 75 μm and below 30 μm grinding using ball mills becomes uneconomical.

The material remaining after the alumina has been extracted from the bauxite ore is commonly termed "bauxite residue". Due to the relatively low grade of Darling Range bauxite, bauxite residue is produced at a rate of approximately two dry tonnes per tonne of alumina. This material is stored in the RSA located to the west of the refinery.
