説明
The distribution of Mg2+, Mn2+, Fe2+, Co2+, Ni2+, Zn2+ and Ca2+ between FeWO4 (ferberite), MgWO4 (huanzalaite) and 2M aqueous chloride solutions was experimentally investigated under supercritical hydrothermal conditions of 500 to 800°C, 1 kb and 600°C, 0.5 to 2.0 kb.<br>The experimental results revealed that the cations were taken into solid phases (ferberite and huanzalaite) selectively in the following order: <br>Ni2+>Mg2+≥Fe2+>Mn2+=Co2+>Zn2+>Ca2+.<br>The obtained partition coefficient - ion radius (PC-IR) curves mark a peak around Fe2+. However partition coefficients of Zn2+, Ni2+ and Mg2+ deviate from obtained PC-IR curves. Zn2+ shows a negative anomaly the same as other minerals with 6- or 8-fold sites. On the other hand, Ni2+ represents a positive anomaly. As for Mg2+, its partition coefficients locate on the estimated PC-IR curves at 500°C. However Mg2+ shows a positive anomaly with increasing temperature
