Iron ore sample found is a part of banded iron ore formation. Hematite and goethite are major constituents of iron ore samples. Hematite in the ore sample occurs as specularite with inter granular micro-pore spaces. Goethite is profuse and occurs as colloform product in cavities in addition with the weaker bedding planes.

With 5 mines, 4 processing hubs and 2 port facilities, our Pilbara iron ore business is all connected by more than 1,000 kilometres of rail infrastructure. At each mining hub ore from the mines is crushed, beneficiated (where necessary) and blended to create high-grade hematite lump and fines products.

Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores. Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with “Sub-A” Flotation to produce concentrates that average better than 62% Fe with less than 9% SiO2 and with a

Mining and processing hematite and magnetite ores. High-grade hematite ore is referred to as direct shipping ore (DSO) as, once mined, the ore goes through a simple crushing and screening process before being exported for steel-making. Australia's hematite DSO from the Hamersley province averages from 56% to 62% Fe.

Iron Oxides—Fe 2 O 3. Hematite /Itabirite—Research and actual field use has shown hematite to be an excellent alternative to barite. Hematite is an ore composed chiefly of a soft micaceous hematite and small amounts of quartz. The micaceous hematite is very thin tablets or leaves of irregular outline, and the quartz is an aggregate of grains.

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Iron ore is the source of primary iron for the world's iron and steel industries.

Processed magnetite ore has fewer impurities than hematite ore; and in this way, the elevated cost of processing magnetite ore can be balanced out with the premium pricing that it attracts. Macarthur Chief Executive Officer Andrew Bruton says the company is well advanced with its magnetite project and well placed to process material that export markets will demand.
