説明

Experiments on the simultaneous partitioning of divalent metal ions were performed in the systems (1) ZnS (sphalerite)−(Ni2+, Co2+, Fe2+, Mn2+, Cd2+)Cl2−H2O and (2) Mn3Al2Si3O12 (spessartine)−(Ni2+, Mg2+, Co2+, Zn2+, Fe2+, Ca2+)Cl2−H2O in the temperature range of 500 to 800°C at 1 kb. In the former system for ion partitioning in the 4-fold coordination, parabola-shaped PC-IR curves with a peak near Zn2+ were obtained and no anomaly was observed for Zn2+ and Ni2+ but Cd2+. In the latter system for ion partitioning in the 8-fold coordination, parabola-shaped PC-IR curves with a peak near Mn2+ were obtained, but Zn2+ deviates from such a trend and tends to concentrate into aqueous chloride solutions. The PC-IR curves for spessartine are gentle compared with those for sphalerite. The PC-IR curves both for spessartine and sphalerite become gentle with increasing temperature.
