N2 - The solubility and precipitation kinetic of siderite were measured under 90, 120, and 150 °C, with 1m of NaCl under unchanged pH (pH=6). The solubility data were in agreement with SSP prediction and a diffusion-controlled precipitation was determined for siderite with an active energy of 5.66 kJ/mol. Furthermore, temperature-driven phase transformation was imaged by SEM, in which multiple crystal were observed co-existing under same experimental condition. We discuss the mechanism of transformation among chukanovite, siderite, and magnetite; and how it can attribute to the difficulty in measuring siderite solubility and precipitation kinetic. Lastly, we outline some future work in optimizing our study. Overall, this method can be used for extensive investigations in additional factors that affect the siderite formation, such as ionic strength, pH, CO2 partial pressure, and the presence of inhibitors.
