Developments in the physical separation of iron ore
Jan 01, 2015 Figure 9.8 presents a typical flow sheet for processing a magnetite ore using multiple stages of low-intensity magnetic drum separators. The ore consists predominantly of magnetite and quartz. There are three stages of ball mill grinding and magnetic separation, using low-intensity magnetic drum separators to reject quartz as early as possible.

Any non-magnetic material which has been released by the rod mill is separated and sent to the tailings thickener. Magnetite iron ore particles are separated by the magnetite separator from the gangue (waste material) minerals in the cobber magnetic separators. This material flows to the ball mill for further size reduction.
