91;The main iron ore mineral was oolitic hematite and the head grade was 37.5% Fe. The ore was ground to 60% passing 74 µm, 1 kg/t sodium silicate added and the ore was
61;As high-grade iron ore deposits are gradually being depleted, more difficult-to-process ores such as goethite-rich, low-grade iron ores and tailings are now being processed.
43;This processing, however, produces ore with more iron content, fewer impurities and less waste rock (known as gangue) than hematite. It’s also, as the name suggests, magnetic.
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
Hematite is iron oxide, a weakly magnetic iron mineral with an iron content of up to 70%. Mineral separation is the process of converting raw ore into high

Iron content is a critical specification for hematite iron ore, directly influencing its quality and the efficiency of the iron extraction process. Hematite iron ore typically contains between 45% to
57;Description and properties of common iron ore minerals. Iron ore minerals are rocks or minerals that contain iron in concentrations high enough to be economically extracted.
121;Iron ore pellets are one of the significant sources of iron for iron and steel making due to their superior metallurgical performance, low energy consumption, and less
