For a single mine, average comminution energy consumption can be approximately 6,700 kWh /kiloton. Grinding is accomplished by abrasion and impact of the ore with moving media such as rods (rod mills), balls (ball mills), or pebbles (sized ore in AG & SAG mills). These vary in size according the size of particle being processed.
