Characterization of lacustrine iron sulfide particles with proton-induced X-ray emission. [PDF]
Black particles, collected by filtration (1.2~pm pore size) from the anoxic waters of a soft-water lake, were examined by a scanning proton microprobe which permitted quantitative elemental analysis by proton-induced X-ray emission (PIXE) and Rutherford ...

Influence of structural and textural features of ores and rocks on mine dust explosion hazard during development of pyrite deposits [PDF]
In the practice of mining works, sulfide-dust explosions often occur during underground development of pyrite ore deposits: copper-zinc, lead-zinc, copper-nickel, antimony, and others. This makes it necessary to conduct researches aimed at improvement of
