AG mills crush the ore without the need for iron or steel grinding media. They are used when the ore is hard enough for the tumbling ore to grind itself. In SAG milling, ∼ m 3 of 13 cm diameter iron or steel balls are added into the mill per m 3 of ore (, 15 vol.% "steel") to assist grinding. SAG mills are much more common.
The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure (based on Ref. [4]).This type of flow sheet is usually followed when the crude ore contains below 30% iron.

Iron is harder than most stones. According to the traditional iron ore processing process, the jaw crusher is used for rough crushing, and the ore is subjected to primary rolling from large pieces to small pieces. The counterattack crusher performs the second crushing, and finally the cone crusher controls the size of the ore particles.

The rock breaks and falls out the bottom. These types of crushers are usually applied as tertiary or quaternary crushers with less than 2" (75 mm) feed or smaller. Some Vertical Shaft Impactors can be used as secondary crushers with larger feed. Vertical Shaft Impactors are very applicationspecific. They are sensitive to abrasive materials ...
Hematite and magnetite are the most prominent iron ores. Most of the highgrade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− + mm) and fines (approximately − mm) products.
Abstract Hematite and magnetite, the two predominant iron ores, require different processing routes. Highgrade hematite direct shipping ores generally only require crushing and screening to meet the size requirements of lump (typically between 6 and 30 mm) and fines (typically less than 6 mm) products.
