2. Structure and Properties of Magnetite. Magnetite, Fe 3 O 4, an iron oxide, has an inverse spinel structure (Figure 1).The details of its structure were first established in 1915 by W.H. Bragg [], who provided one of the first mineral structures determined using the X-ray diffraction method.Magnetite has a cubic unit cell with a lattice constant of a = …
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 ...

The black sand magnetite is a raw material to produce iron and steel. High content magnetite in the top meter beach sands of the north-west of El-Burullus Lake of Egypt is separated and mineralogically and geochemically investigated. Magnetite content obtained by laboratory techniques varies between 2.92 and 0.11 wt%, with 1.15 wt% …
