摘要：

Recent evidence, based on spectrophotometric analysis of ethanol extracts, for elemental sulphur being present at the surface of sulphide minerals dry-ground in air has been re-examined. Analysis of ethanol and cyclohexane extracts of ground galena, and electron spectra of abraded galena surfaces, have revealed that while ethanol does extract or leach a sulphur species from galena, sulphur is not present in elemental form on a freshly ground mineral surface.
