Sažetak

U ovom radu prikazani su rezultati ispitivanja uticaja temperature na flotabilnost i stepen dekarbonizacije antracitnog uglja, odnosno desulfurizacije minerala jalovine. Ispitivanja zeta-potencijala, prirodne flotabilnosti i kinetičkih parametara oksidacije vršena su na čistim uzorcima zagrevanjem na niskim temperaturama od 50 do 200˚C. Dobijene zavisnosti između zeta-potencijala, flotabilnosti i temperature potvrđuju negativan uticaj temperature na flotabilnost i iskorišćenje uglja u proces flotiranja uglja.
