The fragility of ore depends upon its strength. In a crushed product or mining product, the fragile ore degen-erate to a undesirable fine product during blasting, excavation, loading and transportation. Similarly in a crushing and comminution process by crusher, ball mill or rod mill, as the ore of high strength attains to a desired size, the fragile ore degenerates to superfine.
