Morphological and mineralogical forms of technogenic magnetic particles in industrial dusts

► TMPs could be distinctive for pollution source identification. ► Magnetite or maghemite spherules are typical for hard coal ash. ► Hematite is more common in lignite ash decreasing their magnetic susceptibility. ► Metallic Fe and ferrimagnetic pyrrhotite are characteristic components of coke dust. ► Ca-ferrite is characteristic ferrimagnetic mineral for cement dust.
