Journal of Siberian Federal University. Engineering & Technologies 2 (2011 4) 123-131 ~ ~ ~ УДК 548.6:549.322.21:549.521.5 Pilot Study of Isothermal Crystallization of Goethite from Metastable Synthetic Pyrrhotite Viktor V. Onufrienok* and Anatoly M. Sazonov Siberian Federal University, 79 Svobodny, Krasnoyarsk, 660041 Russia 1 Received 5.04.2011, received in revised form 12.04.2011, accepted 19.04.2011 The crystal structure and the phase composition of synthesized pyrrhotite after its endurance in the atmosphere of the Earth for 29 years at temperature about 20ºС have been studied using the methods of X-ray structural analysis. Pyrrhotite contained goethite which was absent in initial samples. The analysis of the experimental facts allows to assume that goethite originated from pyrrhotite in a metastable phase. The regularity of goethite formation depending on the percentage of troilite and also on the sulphur and iron ratio in samples has been investigated. The diagram of goethite – troilite phase ratio has been constructed. The theoretical model of phase transition of pyrrhotite into goethite is offered. Good conformity of the calculated curve of the goethite – troilite phase ratio diagram with the experimental one has been obtained. The calculations done in the offered model of secondary quantization cohere well enough with the similar calculations done within the model of a molecular fi eld. Keywords: pyrrhotite, goethite, crystal structure, phase composition, synthesis, metastable state. Introduction Nowadays the interest to the minerals containing the hydroxyl group (OH) in their structure has increased signifi cantly. Goethite FeO(HO), hydronium Fe (SO4 (SO4 ) 2 ) (OH) 2H2 (OH) 5 2H2 O, parabutlerite Fe O etc. can serve as examples of such minerals. This interest can be explained by the fact that their formation is supposed to be connected with hydrothermal metasomatic processes. Such processes are widely developed in volcanic zones on dry land and in oceans. Studying of natural minerals in such zones is actual from the point of view of theoretical and practical geology. It should be noted that the oxidation processes of multi-component alloys have their own features [1]. Ocean pools contain large volumes of valuable mineral resources. In particular, iron-manganese concretions and sulphide accumulations with gold and platinoid admixtures in the formations of black smokers are of practical interest. Necessity of detailed study of formation processes for such minerals is obvious, however, they should be divided in, at least, two sections. The fi rst section is studying minerals of ore masses directly in the process of primary ores formation, which, as a rule, are in a metastable phase. The second section of the research is studying the transformation of minerals during ores oxidation, and transition of metastable minerals into the stable phase.
