摘要： An apparatus for processing magnetite iron ore, including an upstream cyclone and a mill for grinding particles, wherein the upstream cyclone is arranged to operate as a splitter by diverting material in an overflow of the upstream cyclone to bypass the mill and by feeding material in an underflow of the upstream cyclone to the mill.

摘要： A method of processing magnetite iron ore, including the step of using a high pressure grinding roller (HPGR) to crush the magnetite. An apparatus for processing magnetite iron ore, including a first high pressure grinding roller for crushing the magnetite, a dry screen for selectively feeding back material to the first high pressure grinding roller, an air classifier for selectively feeding back material to the second high pressure grinding roller, a second high pressure grinding roller for grinding the magnetite, and a dry magnetic separation (DMS) unit for discarding non-magnetic materials, wherein the dry magnetic separation unit is outside the two feedback loops associated with the first and second high pressure grinding rollers.
