Abstract
The experimental data for ion exchange equilibria between (Fe, Mn, Mg)TiO3 ilmenite solid solution and 2N (Fe, Mn, Mg)Cl2 aqueous chloride solution by Kubo et al. (1992) were re-analyzed taking into consideration the formation of FeCl3-aq and MnCl3-aq. As a result, the newly obtained excess Gibbs energy of mixing for (Fe, Mn, Mg)TiO3 ilmenite solid solution was slightly smaller than that obtained by Kubo et al. (1992), where 2N (Fe, Mn, Mg)Cl2 aqueous chloride solution was assumed as an ideal solution.
