Analysis of Water Produced during Thermal Decomposition of Goethitic Iron Ore

Tao Kan, Vladimir Strezov, Tim Evans, and Peter Nelson
Abstract—The aim of this study was to investigate the non-ferrous elemental composition of water produced during thermal decomposition of goethitic iron ore. A typical goethitic iron ore was heated, while the released vapour was condensed by liquid nitrogen trap, and the elements contained in the condensate were measured and grouped. Results showed that Ba in the group of alkali and alkali earth metals, Mn, Ni, Cu, Zn, and Hg in the group of heavy metals, and P and S in the group of non-metal elements were the most abundant elements with present in the chemically bound water. Other technologies including thermogravimetric analysis, Computer Aided Thermal Analysis, and Fourier transform infrared spectroscopy were also used to reveal the thermochemical behaviour of goethite during its thermal processing.

Index Terms—Goethite, decomposition, heat of reactions, FTIR.
