Iron Ore
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.
