Abstract :The thermal behavior of chalcopyrite ore concentrate was used thermogravimetric analysis insert ignore into journalissuearticles values(TG); coupled by differential thermal analysis insert ignore into journalissuearticles values(DTA);. The thermal analysis were done up to 900 o C from 0 o C at different heating rates insert ignore into journalissuearticles values(2, 5, 10, 15 and 20 o C /min); under air atmosphere. The ore was calcined at 30, 60, 90 min and 350, 400, 450, 600, and 800 o C 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.
