Hematite currently dominates iron ore mining - the bulk of direct shipping ores (DSO) are hematite such as Australia's Pilbara mid-grade iron ore. Magnetite ores tend to have a much lower Fe content but are often suitable for significant beneficiation -- in part because magnetite is magnetic which can make separation easier -- to DR-grade.Web
