Iron Ore Pellets and Pelletization Process – IspatGuru

2014-11-26  Iron Ore Pellets and Pelletization Process. Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process.

Iron Ore Pelletizing Process: An Overview

2018-7-17  Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizingprocess since the beginning of pellet production in the 1950s. Bentonite promotes the forma-tion of ceramic bridges between particles, which can minimize the number of pellets thatcollapse during firing. Despite its low cost, the inorganic compounds from bentonite arecontaminants increasing the amount of acid gangue in the pellet.

Beneficiation Plants and Pelletizing Plants for Utilizing ...

2015-1-27  Flotation separation is a technique utilizing the difference in the hydrophilicity of ore surfaces. This technique is used for raw materials with small diameters of approximately 0.01mm to 0.1mm and is often applied to the final stage of grade improvement, or to the removal of impurities such as sulfur and phosphorus. The iron ore and major impurities have a similar hydrophilicity; but adding a chemical (collector agent) that is adsorbed selectively to either iron ore or impurities makes the surface with the adsorbed agent hydrophobic. Air bubbles are then charged from the bottom to be trapped by the hydrophobic surfaces, after which, they float up due to the decrease in density caused by the trapped air. This phenomenon is used to accomplish flotation
