Trends in der Minenindustrie Mineral Processing
Typical types of mill used in ore beneficiation are autogenous (AG) and semi-autogenous (SAG) mills together with ball mills to, for example, obtain particle sizes smaller than 100 µm. One process variation that has become increasingly established in recent years is the combination of AG or SAG mill with a ball mill and a downstream agitatedThe Zourerat iron ore mine has two 1.7 m diameter × 1.8 m wide HPGR units treating 1400 t/h each of aerofall mill pebbles. The feed is − 25 + 1.6 mm and has a ball mill work index of 12–14 kWh/t. The iron ore has low to moderate abrasion characteristics.

Physical separation of iron ore: magnetic separation
In summary, magnetic separation should always be given priority when designing iron ore beneficiation flow sheets. For some oxidized iron ores, the selectivity of high intensity and high gradient magnetic separators may not be as good as desired. The feed ore is first ground using ball mills down to about 90% −75 micron particle sizeA laboratory scale ball mill was used to conduct the grinding tests for PGE bearing chromite ore.
