Streszczenie: Oxidation of waste slag from copper production was studied in oxygen-nitrogen gaseous mixtures (21, 43, 63 and 100 vol.% of O2) under non-isothermal conditions using DTA-TG analysis at constant gas flow rate of 30 ml min-1 and varying heating rate. The results revealed that the mechanism of slag oxidation does not change with changing the oxygen content but intensification of the process occurs. Kinetic analysis was performed and a decrease in the values of the activation energy was observed with increasing of the oxygen partial pressure.
Słowa kluczowe: copper slag oxidation, thermal analysis, dta-tg, kinetic analysis, activation energy
