Pyrite is the most abundant metal sulfide in Earth's crust and also found on Mars. It can form by direct hydrothermal precipitation or polymorphic phase transformation from marcasite. However, control dynamics of pyrite poorly understood, kinetics marcasite to unknown. To address these issues, we quantified formation fluids at pH 1, using pyrrhotite as a precursor mineral produce supersaturated solutions. In situ powder X-ray diffraction experiments 190 °C showed that rich ΣS(-II) (0.2...
A flow-through reaction cell has been developed for studying minerals leaching by in-situ time-resolved powder X-ray diffraction, allowing a better understanding of the mechanisms and kinetics. The capability independent control temperature (up to 95 °C) flow rate (>0.5 mL min−1) atmospheric pressure leaching. It was successfully tested at diffraction beamline Australian Synchrotron. Galena leached in citrate solution under condition 0.5 min−1, while patterns were collected during entire...
