Iron ore processors may also employ magnetic separation for beneficiation of classifier output streams. Wet high-intensity magnetic separators (WHIMS) may be used to extract high-grade fine particles from gangue, due to the greater attraction of the former to the applied magnetic field.

Iron beneficiation has been evident since as early as 800 BCE in China with the use of bloomery. A bloomery is the original form of smelting and allowed people to make fires hot enough to melt oxides into a liquid that separates from the iron. Magnetic separation is used to separate magnetic gangue from the desired ore, or conversely to

Concentration of iron ore with low-intensity magnetic separators has been used for decades in the recovery of magnetite. While gravity separation and froth flotation are two important processes for mineral beneficiation, other methods can be used to concentrate minerals and separate them from gangue and each other.

Shandong 1500t/d Iron Ore Beneficiation Project. Xinhai increased anionic reverse flotation process of magnetic concentrate on the basis of the single magnetic separation process. Iron ore concentrate was obtained directly with a roughing, tailings were discarded with three scavenging, middlings returned to efficient thickener.

Natural iron ore like magnetic iron ore or hematite iron ore can make ore beneficiation after series of measures. The following is the process of ore separation: 1.Natural iron ore after coarse broken, then it will be further broken by Crusher.(Or use one-stage ball mill and two-stage ball mill to make ore grinding).
