magnetic separation iron ore
Gravity separation and magnetic separation are mainly used to separate coarse-grained and medium-grained weakly magnetic iron ore (20~2 mm). During gravity separation, heavy medium or jigging methods are commonly used for the gravity separation of coarse and very coarse (>20 mm) ores; spiral chutes, shakers and centrifugal concentrators for medium to fine (2~0.2mm) ores, etc. Reselect method.

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, ∼0.15 m 3 of 13 cm diameter iron or steel balls are added into the mill per 0.85 m 3 of ore (i.e., 15 vol.% “steel”) to assist grinding. SAG mills are much more common.
