Magnetite forrnation by the reduction of hematite with iron RRuff. The formation of magnetite by the reduction of hematite with iron in the presence of aqueous solution at 350570"C, 12 kbar pressure, takes place by two reactions: (l) the oxidation of iron metal with water, and (2) the reduction of hematite .
The preparation of magnetite (Fe 3 O 4) has become of longstanding interest because of the diversified applications of magnetite in the industry as a pigment, in magnetic tapes, or as raw material for ironmaking [1,2,3].Therefore, it is of great interest to study innovative synthetic methods to reduce the production costs of magnetite and improve its production efficiency.

Mill scale iron waste has been used to prepare some iron oxide pigments via specific precursors. Magnetite and goethite were precipitated from their respective precursors in aqueous media. Various red shades of hematite were prepared by the calcinations of the precipitated goethite at temperatures ranging from 600 to 900 °C.
Iron oxide are a group of compounds made up of iron and oxygen linked together by chemical bonds. The rust you see on metal is an example of natural iron oxide formation. Rust forms when iron is exposed to oxygen and water, and a chemical reaction called oxidations occurs.
Magnetite concentrate was recovered from ferrous sulphate by coprecipitation and magnetic separation. In coprecipitation process, the effects of reaction conditions on iron recovery were studied, and the optimal reaction parameters are proposed as follows: n(CaO)/n(Fe 2+) :1, reaction temperature 80 °C, ferrous ion concentration mol/L, and the final mole ratio of Fe 3+ to Fe 2+ in ...
