Ball mills have shells of cast iron or steel plates and are carried on hollow trunnions. Ore is fed through a scoop, drum-type, or combination feeder at one end and is discharged from the opposite trunnion. Ball mills may be arbitrarily classified into two types, according to the method of pulp discharge.

The grinding is currently done in four wet mills. Ground ore is then concentrated in the spiral plant using gravity spirals to increase the iron content from 38% to approximately 65%. The spirals utilize the forces of gravity, centrifugal action and friction to separate the heavier iron ore grains from the lighter waste rock particles.
