The processing of iron ore requires physical processes that help ensure conformation to sizing specifications and where required help the ore achieve grade targets. The sizing separation of iron ore is achieved through the comminution and screening processes described in Chapter 8. This chapter is concerned with the further physical separation processes applied to both coarse and fine portions of comminuted iron ore
