ore quality is to produce ore of consistent grade (not only in iron, but also in phosphorus, silica, and alumina). Traditionally this is achieved by blending from intermediate stockpiles, but this imposes large handling and stock costs which would be avoided if the desired grade uniformity can be achieved with less rehandling of the ore.
