We possess the technical skills required to beneficiate and process iron ore into iron ore pellets. Over many years we have made significant investments in our processing capability which allows us to produce consistently two types of pellets; 62% Fe and 65% Fe. The diagrams below provide an overview of the production process. To find out more about our pellets see High quality output.
Ore from mine
Open cut, hard rock iron ore mining, using truck and shovel. Average Fe content of 30%.
Medium fine crushing
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
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.
Wet magnetic separation
The fine ore particles are collected to produce 63% Fe concentrate, half of which goes to 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.
We transport our finished products by rail to border dispatch points. From the border points, the means of transportation include rail, barges and capesize vessels.
