[email protected]The direct reduction of iron-ore fines without an intermediate agglomeration stage has been an interesting challenge for process developers in the past. The constraining factor has been the so-called stickingtendency of reduced or metallized fines, which is particularly prevalent and difficult to control in the case of gas-based direct reduction.
