Program 1 - RP1.012
Overview
The steel industry needs to de-carbonise, with a likely low carbon route being the production of steel from hydrogen direct reduced iron (DRI) using existing or emerging fluidised bed processes (CIRCORED, HYFOR, HYREX), followed by melting in an electric furnace.
At present Australian iron ores are utilised in the traditional blast furnace ironmaking process, with no current supply to DRI processes. The suitability of Australian ore fines and magnetite concentrates as mined/after beneficiation needs to be assessed in fluidised bed processes with particular emphasis on maximising operating temperature while preventing sticking. However, the reduction kinetics of Australian ore fines in a fluidised bed reactor are relatively unexplored.
