Within the MHA binder-water-iron ore system in pellets, the pH value has an important effect on the adsorption behavior of MHA binder, and also on the pelletizing process [13]. In such MHA binder-water-iron ore suspension system, there should be many different kinds of metal cations dissolving from the surface of iron ore particles.

Iron ore pellets are spheres of typically 8-16 mm to be used as feedstock for blast furnaces. They contain 64-72% iron and additional materials, which can adjust the chemical composition and metallurgical properties of the pellets. The iron ore pelletization is the process of converting iron fines less than 200 mesh (0.074 …

Pelletizing. Pelletizing is a method for forming nearly spherical powders, based on roasting and consolidating green pellets prepared by adding proper amount of water and binder into fine materials or fine concentrates. Pelletizing is one of the important methods of agglomeration of iron ores, by which pellets are produced.

ABSTRACT The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet. Meeting these requirements …

Iron ore production in 2019 is estimated at 2.850 billion tonnes, and according to conservative forecasts, global iron ore production is expected to reach 3.119 billion tonnes by 2028, an annual increase of only 0.9%. In contrast, global pelletizing capacities are expected to increase by 5.5 % per annum until 2025. These

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. In the STG process, a stationary bed of pellets is ...
