Every 24 hours, around 180,000 tonnes of ore are fed into the six milling lines' autogenous grinding mills (AG mills), these are the largest grinding mills in the world. Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart.

The hardness and related characteristics of ore are obviously important factors in its grinding and beneficiation, as well as the amount of lump ore obtained, as it often attracts a premium price over fine ore. Lump ore is defined as having a nominal particle size of 31.5–6.3 mm, whereas particles less than 6.3 mm are known as sinter fines.

Based on the design throughput, run-of-mine (ROM) ore maximum lump size and ore comminution characteristics, a single gyratory crusher 1,600 mm by 2,400 mm (63" x 95") or equivalent has been selected for primary crushing run of mine ore at a rate of 3,274 t/h based on availability of 70% for 6,100 hours operating per year.
Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.

ore is in the form of fine particles, as small as 0.1mm or less, which are not suitable for sintering. This issue led to the use of pelletizing. Pelletizing plants are expected to play an important role in an era when the global reserve of high-grade lump ore is shrinking. The plants promote the concentrating of low-grade ore into
Iron ore fines are generated by crushing and grinding lump ore. If the lump is of low grade that is low in iron content and higher in impurities such as SiO2 and Ai2O3, the fines must be benefitted before being feed to the blast furnace. 13.
