hematite ore has the chemical formula fe2o3 and has a very high iron content of 70 percent. its name comes from the greek word for blood,
mined as the main ore of iron, it is much harder than pure iron, yet much more brittle. its spectral signature has been detected via infrared spectrometer on the
iron ore sintering has developed to enable the incorporation of a wide variety of iron ores, i.e., outside traditional hard hematite ores.
chemical formula: fe2o3, iron oxide class: oxides and hydroxides group: hematite uses: very important ore of iron, as a pigment and as mineral specimens.
hematite gets its name from a greek word meaning 'blood-like.' this refers to the red color of the powdered mineral. this mineral is the primary ore from which
the iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite,
hematite (or haematite). hematite is the most important ore mineral of iron. it is an oxide mineral and is found in a variety of colours, with red, orange and brown
hematite has traditionally formed the bulk of global iron ore production, and high-grade hematite is often referred to as direct shipping ore or dso because it is
