· Conclusion. The literal answer to the question posed by the title of this contribution is yes, progress in energy-efficient comminution is doomed, if by ‘energy-efficient comminution’ we mean trying to beat the physics. There are fundamental limits to what can be achieved by mechanical breakage of rock.

· 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.
