Iron ore beneficiation technology and process,gravity and
Gravity separation and magnetic separation are mainly used to separate coarsegrained and mediumgrained 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 (gt;20 mm) ores; spiral chutes, shakers and centrifugal concentrators for medium to fine (2~) ores, etc. Reselect method.
