the ore to yield an upgraded product substantially low in alumina. To utilize the large amount of iron-ore fines produced during mechanized mining and in the ore-handling plants, the provision of sintering facilities has been proposed in almost all the steel plants. Generally the fines have higher alumina and silica contents than the lumpy ore.
