Open cut, hard rock iron ore mining, using truck and shovel. Average Fe content of 30%.
The ore is crushed and screened to allow it to be upgraded through separation by two crushing plants.Input particle size: 0-1,200mm, output particle size: 0-20mm.
Dry magnetic separation separates waste material from the iron resulting in output particles of 0-20mm with a Fe content of 40%.
The ore is ground to produce fine particles of 0-0.44mm in size.
The fine ore particles are collected to produce 63% Fe concentrate, half of which goes the pelletiser to produce 62% Fe iron ore pellets.
Approximately 50% of the concentrate is upgraded to 67% Fe content, used to create 65% Fe iron ore pellets, with unwanted waste material removed to the tailings storage area.
Four kiln grate units which heat and form the materials into pellets of around 16mm.Temperature of pelletising kiln: 1,250ºC.
The iron ore pellets are transported by rail, barge and sea to customers around the world.
