Good fragmentation results in significant benefits down the value chain, particularly in the loading and hauling operations and the crushing circuit of a mining operation (Phamotse and Nhleko, 2019). The use of chemical energy, in the form of explosives instead of mechanical energy to break the rock is widely accepted as cheaper and more efficient.

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.
