How Ores have Resistance to Crushing

The apparent work is in turn inversely proportional to the resistance of the ore to crushing ; hence, the area between the curves is inversely proportional to crushing resistance. Unfortunately, we are unable to deal accurately with the material below 200 mesh, which is where most of the work done is represented.
