Rough bauxite stone. Bauxite is a sedimentary rock that consists mainly of the basic aluminum oxide mineral gibbsite [aluminum hydroxide, Al (OH)3], and the dimorphic minerals böhmite and diaspore [both basic aluminum oxide, AlO (OH)].

3.1 Introduction to Crushing and Grinding of Bauxite. The most common initial process step to feed an alumina refinery with bauxite is the crushing or sizing of the raw bauxite material that is extracted from the mine. The feed material is crushed or sized so that it is conveyable, as well as correctly dimensioned, for the next step in the process.Web

Resourcing of research and development projects. Bauxite mining consumes a relatively small amount of energy (and consequently has low greenhouse gas emissions) compared to alumina refining and aluminium smelting processes. Diesel fuel and fuel oil combustion provides the bulk (95%) of the energy required to extract and haul the mined ore.Web
