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.
Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

Iron ore is transported from the mine to the steel mill through a supply chain that includes mining, processing, and transportation. The supply chain can be complex, with multiple stakeholders involved in each step of the process. To ensure a reliable supply of iron ore, steel companies often sign long-term contracts with mining companies.
Iron ore mining operations Pilbara region Western Australia. The process of iron ore mining. Mining iron ore is a physically and chemically demanding process that takes place in remote locations around the world. The process begins with exploration, which can be done through surface or underground methods. Once a deposit is discovered, mining ...
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 …
