Abstract: 
Reducing specific CO2 emissions is a high priority task of the industry. The state of the art technology of the iron- and steel industry contributes to CO2 emissions during the iron ore beneficiation [1] to a significant amount. By remodeling the technology, these CO2 emissions can be reduced tremendously [2]. Direct iron carbonate (FeCO3) reduction with hydrogen is an alternative pathway to state of the art iron ore beneficiation with significantly less specific CO2 emissions.
The outcome of the design of experiments showed that the factors process temperature, particle size, gas flow and the interaction of gas flow*temperature and gas flow*gas flow were identified as strong impact on FeCO3 conversion.
