Iron ore | BHP
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.

Iron ore beneficiation: an overview
Dry processing of iron ore: In dry processing of iron ore, ROM is generally crushed below 40 mm through three-stage crushing and thus segregated by screening into 10–40 and −10 mm fractions. For softer ore, tumbler index is generally low and hence lump ore is crushed below 10 mm to produce fine product. Yield from the plants has …

Iron ore mining and dressing
An ironworks (or iron works) is an industrial plant for the production of steel from iron ores! Before the iron ores can be fed to the ironworks, they must first be mined (ore extraction) and specially processed for the blast furnace process (ore processing). These process steps are described in more detail in the following sections.

The estimated greenhouse gas emissions were 11.9 kg CO 2 e for mining and processing 1 tonne of iron ore. The embodied energy values were 153 MJ/t ore for iron ore. The results showed that loading and hauling made the largest contributions (approximately 50%) to the total greenhouse gas emissions from the mining and processing of iron ore.
