The mechanism of formation of iron oxide and oxyhydroxides in
The formation processes on which end products are determined are strongly affected by the oxidation rate pH and the structure and composition of initial and intermediate species of iron. The systematic diagram of formation processes of iron oxide and oxyhydroxides has been presented in which both dissolved and solid species of iron are included.
Process for the production of iron oxide C K WILLIAMS and CO
A cyclical process for producing red iron oxide which comprises dissolving iron in dilute sulfuric acid crystallizing and separating FeSO4.7H20 from the solution drying and dehydrating the FeSO4.7H20 to obtain FeSO4.H20 decomposing the FeSO4.H20 by heating the same indirectly in a substantially closed heating zone to a temperature between
Iron II hydroxide Wikipedia
Iron dissolved in groundwater is in the reduced iron II form. If this groundwater comes in contact with oxygen at the surface e.g. in natural springs iron II is oxidised to iron III and forms insoluble hydroxides in water. The natural analogue of iron II hydroxide compound is the very rare mineral amakinite FeMg OH 2. See also
