comminution
comminution The liberation of valuable minerals from their ores by crushing and grinding the ore to a particular grain size so that the residue is a mix of relatively clean particles of ore minerals and waste. Comminution is carried out initially to make excavated material easier to handle and of a specific size. Comminution theory is concerned with the relationships between energy input and particle size from a given feed size.
