Popis: In this research, a mineral barite powder was reduced by carbon monoxide gas and the effects of reduction time and temperature was investigated as well as barite particle size. Results showed that the best result would be feasible when the barite particle sizes are between (-70 +100) in mesh scale. The barite reduction could reach the maximum level (98%) after reduction by carbon monoxide at 850°C for one hour. Meanwhile, the same amount of reduction could have been achieved in shorter time intervals at higher temperatures. The kinetics model for reduction process was also determined and activation energy was calculated.
