Before the ore can be concentrated, it must be reduced to "liberation" size-between 8o and go per cent -325 mesh, the fineness of face powder. This is done by running the ore through rod-and-ball grinding mills. The iron is separated from unwanted materials by magnetic separators, and the water is removed from the finished concentrates by filters.
