Introduction. Grinding operation is used extensively in the industry of beneficiation, metallurgy, chemical engineering, and electric power. Assisted by the impact and abrasion between media (steel ball, steel rod, gravel, ceramic ball) and ore, the grinding operation reduces the particle size in the mill [[1], [2], [3]].

Karara comprises a largescale, longlife magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (3436% Fe) than hematite ore (5864% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a highgrade (+65% Fe) concentrate for steelmaking.
