Effect of Blaine Fineness on the Quality of Hematite Iron ...

+

Iron ore pellets are largely characterized by inherent physical and chemical properties of ore as well as pelletizing conditions including induration time, induration temperature, etc. These parameters essentially vary with types of ores. The production of highquality pellets from hematite ore is challenging because of high level of fineness (Blaine number) and induration temperature ...

­The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ­). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.

I will attempt to describe the iron ore pelletizing process below. In the palletisation plant, a suitable binder such as Bentonite is added to ground iron ore or iron ore concentrate which is mixed in a high intensity mixer. In order to harden the pellets, they are heated to temperatures between 1290C to 1340C. This treatment can sometimes ...
