Iron ore processing. For iron ore extraction, the iron ore processing plant receives ROM where it undergoes crushing and subsequent screening on a grizzly screen. It is then sized and above cut point ore sent for further crushing and additional sizing; Coarse material has tramp removed via an overbelt magnet and into a DMS drum
