Abstract
The gas-based direct reduction of iron concentrate pellets was carried out by using the typical carbon monoxide. The investigation on the influences of time and temperature of the reduction were studied. The results showed that the temperature and time of the reduction were directly related to the reduced iron content. In order to perform the iron reduction experiment, the powder iron concentrate needed to be pelletized, and the binder agents have used molasses and bentonite. As the result of the reducing experiment at the 1050°C temperature and for 120 minutes, the reduced iron content was 85.6%, and hardness was 115.5 HV which meets the requirements of the reduced iron standard.
