Magnetite has been important in understanding the conditions under which rocks form. Magnetite reacts with oxygen to produce hematite, and the mineral pair forms a buffer that can control how oxidizing its environment is (the oxygen fugacity). This buffer is known as the hematite-magnetite or HM buffer.
Magnetite is a black, opaque, magnetic mineral that leaves a black streak when rubbed across a hard rough surface. It is one of the most abundant metal oxides, and its crystal structure contains both the ferrous (Fe+2) and ferric (Fe+3) forms of iron ions. A complex pattern of electrons between the two forms of iron is the source of its ...

Magnetite ores have gained significant attention in the iron industry. Magnetite is an iron oxide mineral found in metasedimentary and magmatic iron deposits [3]. It is generally black and has high magnetic properties. The latter property is exploited in the beneficiation of magnetite ores using low-intensity magnetic separation.
Synthesis of magnetite. 80 g of mill scale was added into the 2 L beaker containing 400 mL of conc. sulfuric acid and the mixture were digested for 24 h at 70 °C.
