After extraction from the deposit, the iron ore is with high percentages of gangues and impurity material, which is unsuitable for end application. The iron ore must be manufactured in the beneficiation operation. Iron beneficiation is fairly complicated consisting of the following techniques milling (crushing and grinding); washing; filtration; sorting; sizing; gravity concentration; magnetic separation; flotation; and agglomeration (pelletizing, sintering, briquetting, or nodulizing). The most frequently employed method is milling and magnetic separation.

We have delivered and installed thousands of iron processing plant all over the world such as South Africa, India, Indonesia, Kenya, Ghana, Russia, Peru, Canada, Australia, Zimbabwe, Zambia, Brazil etc. If you are interested about iron ore beneficiation plant cost or other information, please contact us.
Crushing is the primary stage in beneficiation operation. Generally, primary crushing as well as screening occurs on the quarry site. Primary crushing is completed by employing gyratory and jaw crushers. Primary crushing delivers ore particles ranging in size from 6 to 10 inches. Oversized material is passed through extra crushers such as impact crusher and cone crusher to obtain the required particle size. The ore is then crushed and sized in an alternative milling facility.
Grinding is essential phase in iron beneficiation operation. It delivers fine particle size and prepares for further procedure. Fine milling further breaks the ore particles to even fine powder about 325mesh. The selection of grinding circuit for iron ore milling operation is dependent on the density and hardness of the ore to be ground. The most popular grinding mills iron ore beneficiation process includes ball mill, coarse powder mill, trapezium mill, vertical mill, ultrafine mill etc.
