In the paper are shown the history, processing and applications of hematite. Hematite is an oxide of iron having the composition Fe2O3. Pure hematite, also called "red ore" contains 70% Fe.
Pure hematite contains 69.9% Fe by molecular weight. It has been the dominant iron ore mined in Australia since the early 1960s. Approximately 96% of Australia's iron ore exports are high-grade hematite, the bulk of which has been mined from deposits in the Hamersley province of Western Australia.
The Blotberget iron ore project is an underground iron ore mine being developed in Dalarnas County, Sweden by Nordic Iron Ore.
The Hematite ore used in this study was collected from Iron ore mine, India. The lump ore was crushed using roll crusher and sieved to get the average particle size 56 µm.
Hematite ore crushing: in this stage there are also three steps, the hematite ore may go through primary crushing, secondary crushing and fine crushing. Hematite primary crushing equipment use PE750*1060 jaw crusher, secondary crushing plants mainly use PEX250*1000 jaw crusher, fine crushing plants mainly use WLF1300 cone crusher.
Hematite is the oldest known iron oxide mineral. Formula Fe2O3. it is the most important ore of iron because of its high iron content and its abundance.
