The thermal behavior of
chalcopyrite ore concentrate was used thermogravimetric analysis (TG) coupled
by differential thermal analysis (DTA). The thermal analysis were done up to
900oC from 0oC at different heating rates (2, 5, 10, 15
and 20 oC /min) under air atmosphere. The ore was calcined at 30,
60, 90 min and 350, 400, 450, 600, and 800oC and investigated
sulphation proportions. The products of obtained calcination were characterized
by XRD, SEM/EDS, FTIR analysis. Based on the conclusions obtained was confirmed
the thermal behavior of the ore.
