Iron ore fines are usually subject to beneficiation and/or pelletisation thereby converting them back into hard rock-like shapes (pellets) with a proper tumbler index; These pellets are then used for making sponge iron. Rotary kilns have a drawback upon the size and quality of iron ore that can be used.
