iron ore milling operation
Duplication of iron ore mining operation, Yandi mine ML 270SA
06.02.1998The proposed second iron ore mining operation, Yandi C1/C2, is located on resources totalling approximately 200 Mt. Lowering of the present water table by approximately 40 m is necessary to recover all of the economic ore. The operation will be serviced by an additional rail spur of approximately 10 km length, terminating in a loop.

Dry Iron Ore Beneficiation
Iron ore extraction is mainly performed through open pit mining operations, resulting in significant tailings generation. The iron ore production system usually involves three stages: mining, processing and pelletizing activities. Of these, processing ensures that an adequate iron grade and chemistry is achieved prior to the pelletizing stage.
