Developments in the physical separation of iron ore

2015-1-1  Figure 9.2 shows a permanent magnetic drum separator, which consists mainly of a permanent magnet system, a rotating drum, a separating chute, a feed tank, and a flushing pipe. For magnetite separation, the magnetic field intensity on the surface of the drum is between 0.1 and 0.4 T.However, for other applications, the intensity may reach as high as 0.8 T.

Mineralisation and Ore Type Karara Mining

Magnetite. Karara comprises a large-scale, long-life magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a high-grade (+65% Fe) concentrate for steelmaking.
