THE CONNECTION CALCINATION AND SULPHATION WITH THE THERMAL BEHAVIOR OF CHALCOPYRITE ORE CONCENTRATE

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.
