Rotary hearth furnaces (RHFs) are used to process solid dust; their key function is to recover iron-bearing solid wastes in the internal system [23,24]. Dust is mixed with carbonaceous material to yield an unprocessed ('green') pellet, which is then reduced in a high-temperature (> 1200 °C) atmosphere while the furnace is rotated [25]. ...
