X-ray Photoelectron Spectroscopy (XPS) was used to study mineral, synthetic and coalassociated pyrites, oxidized for various time intervals at low temperatures with humid air or oxygen. This was done to find out if XPS could detect, monitor and clarify pyrite surface-oxidative changes that influence
binary organic solvent mixtures commonly used in such experiments. By matching coal and solvent solubility parameters swelling is maximized. The experiment takes note, however, of supplementary effects, including those accompanying the entry of solvent into the coal pores. ## 97102613 Thermal and
