Mining and processing of iron ore involves coarse crushing and screening. Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse.

The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with 63.5 % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from 26.5 Mta capacity to 28 Mta in the forthcoming years.

Mechanical screening, often just called scr eening, is the practice of taking g ranulated ore material and separating it into multiple grades by par ticle size. This is called as size control.

The ore goes for preliminary screening, followed by stream sampling, which is a process that uses a hammer sampler. A semi-autogenous mill (SAG) or ball mill is then used to grind and crush the gold ore to a smaller particle size. After this milling, the stream is fed to a trommel screen and next, a cyclone circuit.

There are four stages involved in the production of iron ore pellets.
