Even in mechanical processes such as blasting, crushing, and grinding, the fragmentation of the ore is determined by its mineral content, grain size, texture, and structural fabric, and how these features respond to the particular stresses applied to them.
In mineral processing, all ores will have an optimum particle size which maximizes the economic benefits from the net smelter return while minimizing the cost of crushing and grinding. If the particle size is too coarse there will be inadequate liberation, limiting recovery (and thus revenue) in the separation stage.
