Abstract: This study investigates the fluidized bed roasting process for treating a cobalt-bearing copper concen-trate from overseas, focusing on investigating the key technical parameters of the ore during fluidized bed roasting. Results demonstrate that the optimal fluidized bed roasting conditions include a temperature of 630 °C, air atmosphere, gas-to-feed ratio of 2.2 mkg (operational), and material retention time of 6-7 h. Under these conditions, the roasting slag yield reaches 76.70 %, with a dust generation rate of 33.11 %. Subsequent sulfuric acid leaching of the mixed slag after continuous fluidized bed roasting achieves leaching rates of 96.58 % for copper and 89.57 % for cobalt. Flue gas analysis reveals an oxygen contentration of 2.95 %, SO2 conçentration of 60 900 mg/m3, and CO concentration of 2 130 mg/m3.Relative productivity of recovered dust via gravity, clyclone, and bag filter systems are 52.52 %, 31.62 %, and 15.86 %,respectively. The relative metal contents of copper ard cobalt in the dust account for 19.34 % and 13.53 %, respectively. These results provide solid data for the industrial-scale fluidized bed roasting design of cobalt-bearing concentrates.
