Abstract
The kinetics and the mechanism of goethite formation in the process of iron(II)-sulphate oxidative hydrolysis at pH = 4.5 and temperatures o f 30-degrees and 60-degrees-C were studied by chemical methods, transm ission electron microscopy and Mossbauer spectroscopy. Experimental ev idence was found for the role of iron(II) and the hydrolysis intermedi ates in the formation of a crystalline goethite phase.
