Iron Ore Information
Hematite ore
Hematite iron ore deposits are currently exploited on all continents,
with the largest intensity in South America, Australia and Asia. Most
large hematite iron ore deposits are sourced from met somatically
altered banded iron formations and rarely igneous accumulations.
Hematite iron is typically rarer than magnetite bearing BIF or other
rocks which form its main source or protoplast rock, but it is
considerably cheaper and easier to beneficiate the hematite ores and
requires considerably less energy to crush and grind. Hematite ores
however can contain significantly higher concentrations of penalty
elements, typically being higher in phosphorus, water content and
aluminum.

In Australia iron ore is won from three main sources: isolate "channel
iron deposit" ore derived by mechanical erosion of primary banded-iron
formations and accumulated in alluvial channels such as at Pannawonica,
Western Australia; and the dominant met somatically-altered banded iron
formation related ores such as at Newman, the Chichester Range, the
Hamersley Range and Koolyanobbing, Western Australia. Other types of ore
are coming to the fore recently, such as oxidized ferruginous hard caps,
for instance literate iron ore deposits near Lake Argyle in Western
Australia.
The total recoverable reserves of iron ore in India are about 9,602
million tones of hematite and 3,408 million tones of magnetite. Madhya
Pradesh, Karnataka, Bihar, Orissa, Goa, Maharashtra, Andhra Pradesh,
Kerala, Rajasthan and Tamil Nadu are the principal Indian producers of
iron ore.
