The solubility of SnO2(cassiterite) was studied at 23±2 °C as a function of time (7 to 49 days) and pH (0 to 14.5). Steady state concentrations were reached in <7 days. The data were interpreted using the SIT model. The data show that SnO2(cassiterite) is the stable phase at pH values of < ∼11.7. These extensive data provided a log 10 K 0 value of −64.39±0.30 for the …

The speciation of tin and the solubility of cassiterite in H 2 O + HCl were determined at temperatures to 600 °C using in situ Raman spectroscopy. In addition, information on the fluid-melt partition of Sn was obtained at 700 °C and indicated a preference of the fluid only at HCl concentrations that are much higher than in fluids exsolved from natural felsic melts.
