Iron Ore Pellets and Pelletization Process – IspatGuru

26/11/2014  Hence the iron ore pelletizing process is a chain of several sub-processes which depends highly upon each other’s performance. The addition of binder to the ore serves two main objectives They are (i) to make the ore plastic so that it can nucleate seeds which grows into well formed pellets, and (ii) to hold the pellet together during handling, drying and preheating or until it has been ...

Concentration - LKAB

In the concentration plant, the ore is finely ground and separated in order to remove impurities contained in the ore, such as silicon, sodium, potassium and phosphorus. Grinding is performed in two or three stages, depending on which ore is being concentrated. Grinding and separation are performed alternately, which ensures that impurities are separated from the slurry and that the iron ...
