Iron Ore and Pellets

But, before this, the ore goes through a blast furnace that only works when air can circulate freely. For this reason, the material needs to be big enough so that there are spaces between each piece. On top of this, the ore needs to be strong enough not to be crushed thereby obstructing the blast furnace.
