Iron ore has a sand-like structure that can put out the fire in the furnace. Because of that, you can't put it in the furnace just like that. The ore is first baked to make it into porous chunks, or sinters. This is done in the Sintering Plant. In the Pelletising Plant, we turn the fine ore into small balls in large drums.
