Iron ore | BHP
The crushed ore is sorted over screens and resized to different specifications, such as lump and fines products. Once the iron ore is processed, a stacker builds a stockpile in the stockyards. When ready for transportation, a reclaimer picks up the ore from the stockpiles and conveys it to train load out facilities.

There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red. Iron is responsible for the red colour in many of our rocks and the deep red sands of the Australian deserts.
