The Pilbara region is rich in such hematite ore, known also as "direct shipping ore" (DSO). DSO passes through a simple crushing, screening, and blending process (beneficiation) before it is shipped for steel production. DSOs, when mined, typically have iron (Fe) content of between 56% and 64% Fe.

A crusher is a machine that reduces large rocks into smaller rocks, gravel, or rock dust. Crushers are mainly used in the mining and construction industries, where they are used to break down very large rocks and boulders into smaller pieces. Crushers are also commonly used for jobs like breaking up asphalt for roadwork or demolition projects.

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.
