Stirred media mill decreased bauxite d50 size from 780 to 5 mm in 3 min. But, the ball mill has reduced to 455 mm at the end of the same grinding period. In addition, the energy consumed by the ball mill for similar fineness (5 mm) was approximately 300 kWh/t energy, whereas the stirred media mill consumes approximately 174 kWh/t energy.
— Iron ore is typically extracted from the ground by blasting, then removing the ore using large earthmoving equipment. Bauxite is typically extracted by open-pit mining.
