Abstract: 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.

Abstract: A method of dewatering magnetite to <10% w/w moisture content, including the step of extracting water from the magnetite by virtue of the magnetism of the magnetite, whereby the magnetite pulls together under magnetic attraction thereby squeezing water outwardly and away from the magnetite.

Abstract: An apparatus for processing magnetite iron ore, including a screen arranged to send oversize material to a regrind mill and undersize material to a high grade concentrate thickener and includes a CCD thickener type system for product grade improvements.
