Abstract—
The high-temperature (up to 1000°C) oxidation behavior of natural galena after mechanical activation has been studied by thermogravimetry, differential thermal analysis, mass spectrometry, and X-ray diffraction. The results demonstrate that the nature of the energy stored during mechanical activation of galena influences its reactivity. Mechanical activation has been shown to influence the morphology of galena particles, and we have compared oxidation processes during continuous heating in flowing air before and after mechanical activation.
